KAS Periodic Table
The KAS periodic table reproduces and depicts the nuclear properties of chemical elements. This periodic table depicts not only the trends of nuclear properties, but also reproduces their numerical values that remain very close to the experimental values (difference less than 4%).
The Segre Chart is based on the number of protons, Z, and the number of neutrons, N. It is like a library of nuclei and shows the recorded data only. The Segre Chart can not work when the number of neutrons is not given. But KAS Periodic Table works when the number of neutrons is not given.It does not require the number of neutrons to produce the results.This is a simple chart based on the number of protons of chemical element. We identify the following properties of elements:-
- Location that remains near the Neutron Dripline of element.
- Location that remains very close to stable or long-lived isotopes of the element. Location that remains near the Proton Dripline of element.
- In the case of superheavy elements, we identify which Compound Nuclei are involved in the Hot Fusion reaction and which Compound Nuclei are involved in the Cold Fusion reaction.
- We see the r-process path and assess the r-process abundance.
- The pattern of abundance of chemical elements.
- We identify which elements are the product of exothermal fusion.
- We identify the location of isotope on the basis of two-neutron separation energy.
- Nuclear binding energy trend. Beta decay trend.
- We see the Straight Line of Nuclear Stability.
- Empirical Law discovered.
- Periodicity in the nuclear properties.
- We can compare the nuclear properties of an element with the nuclear properties of almost all the chemical elements.

Harrington Periodic Tables
So we start this effort tabula rasa (without preconceived ideas).
1) All atoms have a default "common denominator" structure at 270 mass units, irrespective of the element under discussion. Therefore, no elements seen as wisps and glints past this point are of consequence. Ergo, the bizarre stability of Dubnium 270.
2) This common structure is divided up by the exact same divisors as are the electron orbitals - i.e. the prime numbers of 2, 3, 5, and 7.
3) Pi as a divisor produces its own, unique and dominating organizational patterns.
4) Each of these sets of plotted nuclide "boxes" use identical formats, but are arranged in vertical columns based on the set of 270 AMUs being divided by these prime numbers. So the 5D Table is 270/5 or 54 AMUs per vertical column/"tower".
5) Each system reinforces unique elemental parameters. The system based on 3/Pi, and its second "harmonic" at 6/2Pi reflects physical properties. The 2Pi configuration almost exactly emulates the "conventional" / Mendeleevian element-based table, except the periods are based upon mass not element count, and these periods do not organize in rows of 18 elements, but rather rows of 44 mass units. The organization/configuration of this default structure is: Pi(Pi^2 + Pi + 1) = 44 This is the primary physical default structure of the periodic table and spectrum of elements, as projected in 3D space, and as perceptible to humans.
6) 5D determines everything with magnetic properties. This disproves every single theory that attributes electron shell behavior as determining magnetic parameters. Clearly here we see that the nucleus is "calling the shots", with electron orbitals conforming as driven. The various red and blue shaded boxes are found at extremes of top and bottom.
7) The system of 7D determines most of all physical parameters of surface and molecular behavior. Here we see surface tension, density, softness and hardness, malleability, boiling and melting points and a few other behaviors. This system of correlation is fully unknown to conventional theory. Notice how superlative parameters bunch at the top and bottom of this configuration.
8) When this system of 270 mass units is divided by 12, for 22 mass units per period, the periodic cycle rate precisely correlates with known Type 1 and 2 elemental superconductors. The physical correlations between periodic repetition at 22 mass units, the 270 count system, and superconductors is also completely novel and not compatible to conventional BCS theory. The correlation between this 22 count system and the three largest cross section nuclides known to man (113Cd, 157Gd and 135Xe) is also completely heretical, however mathematically symmetrical and perfect it may actually be organized.
9) The center portion of this common 270 count structure is named the "Cordillera", for the habit of multiple parallel mountain ridges sharing a common alignment. This area is profoundly affected by Pi-based organizations. The very center at 135Xe indicates that the overall table should terminate at element 108 Hassium at 270 mass units. This has a Proton/Neutron ratio of 3:2. This actual nuclide has very poor stability, unlike Dubnium 105 with 270 mass counts. This nuclide has a ratio of precisely 1:Pi/2, indicating the entire table describes a spectrum of mass organizational states spanning the integer ratio of 1:1 (Deuterium) to 3:2, then on through to 1:Pi/2. Current accepted atomic theories concerning "Islands of Stability" are ridiculous.

Instructables 3D Periodic Table
From Makendo on the Instructables website:
The first periodic table was developed in 1862 by a French geologist called Alexandre-Émile Béguyer de Chancourtois. He plotted the elements on a cylinder with a circumference of 16 units, and noted the resulting helix placed elements with similar properties in line with each other. But his idea - which he called the "Telluric Spiral" (see here), because the element tellurium was near the middle - never caught on, perhaps because it was published in a geology journal unread by chemists, and because de Chancourtois failed to include the diagram and described the helix as a square circle triangle.
Mendeleev got all the glory, and it is his 1869 version (dramatically updated, but still recognizable) that nearly everyone uses today.
This instructable [project] documents my efforts to reimagine a 3D periodic table of the elements, using modern making methods. It's based on the structure of a chiral nanotube, and is made from a 3D printed lattice, laser cut acrylic, a lazy susan bearing, 118 sample vials and a cylindrical lamp.

Mystery of Matter: Three Videos
From Alpha-Omega, three videos about the discovery of the Periodic Table.
The Mystery of Matter: Search for the Elements is an exciting series about one of the great adventures in the history of science: the long and continuing quest to understand what the world is made of. Three episodes tell the story of seven of history's most important scientists as they seek to identify, understand and organize the basic building blocks of matter.
The Mystery of Matter: Search for the Elements shows us not only what these scientific explorers discovered but also how, using actors to reveal the creative process through the scientists' own words and conveying their landmark discoveries through re-enactments shot with replicas of their original lab equipment.
Knitting these strands together is host Michael Emerson, a two-time Emmy Award-winning actor.
Meet Joseph Priestley and Antoine Lavoisier, whose discovery of oxygen led to the modern science of chemistry, and Humphry Davy, who made electricity a powerful new tool in the search for elements.
Watch Dmitri Mendeleev invent the Periodic Table, and see Marie Curie's groundbreaking research on radioactivity crack open a window into the atom.
The Mystery of Matter: Search for the Elements brings the history of science to life for today's television audience.:

Alternative Periodic Table
From Useful Charts:
You'll notice that this periodic table looks quite a bit different from the one you're used to. The traditional periodic table is designed to emphasize the concept of valence, which is important for knowing which elements can easily combine with others to form compounds. In contrast, the periodic table below is designed to simply emphasize the way in which atoms are "built" (specifically, how electrons group together into shells and subshells).
It's based on a design proposed by Edward Mazurs in the 1960s. Like the traditional table, this alternative version can be used to find an elements name, number, atomic weight, state of matter, period, group, and block. However, it also contains detailed information on electron configurations and the different types of electron subshells.

New Rendering of ADOMAH Periodic Table
From Valery Tsimmerman, of the PerfectPeriodicTable.com and the ADOMAH Periodic Table:
"I received email from Dr. Marcus Wolf who is a chemist, working on renewable energy and electrochemical storage in Germany, near Nuremberg. He also lectures at Georg Simon Ohm, Technische Hochschule Nürnberg. Attached to his email was new version of ADOMAH Periodic Table that he created. In this new rendering he is using Jensen's Valence Manifold (VM)."
This is what Dr. Marcus Wolf wrote:
"The first one to come up with the idea of using a valence manifold VM = [e + v] as a label for the groups, was Will B. Jensen. He derived it from the very early attempts of Richard Abegg, who, at around 1904, brought up the hypothesis of 'main- and counter-valences', derived from the observable behavior of elements and their compounds in electrochemical experiments. Eric Scerri is citing Jensen in his latest book, in the chapter about Richard Abegg. But Jensen's proper article from 1983 or so is far more detailed and in his later publications he then introduces the valence manifold concept. Last weekend I accidentally observed another consistency between the G-values and their ordering and the valence electron counts, e. If you fix the e value of the starting group in a given l-block as e(initial), you could generate every G-number of a given group by adding the valence vacancy count, v, to it:
G = e(initial) + v.
"That is another hint for the consistency of the VM labelling concept."

Mikhail writes in his J.Chem.Educ paper DOI: 10.1021/acs.jchemed.7b00242; J. Chem. Educ. 2017, 94, 976?979
"Addition of another s-block to the left of the left-step periodic table [enables it] to be rolled into a spiral so that the left and right s-blocks are merged together and the number of elements is exactly 118. The resulting periodic table is called the "spiral" periodic table, which is the fundamental representation of periodicity":

Restrepo's Similarity Landscape
Building Classes of Similar Chemical Elements from Binary Compounds and Their Stoichiometries by Guillermo Restrepo, Chapter 5 from: Elements Old and New: Discoveries, Developments, Challenges, and Environmental Implications p 95-110.
From the abstract:
Similarity is one of the key concepts of the periodic table, which was historically addressed by assessing the resemblance of chemical elements through that of their compounds. A contemporary approach to the similarity among elements is through quantum chemistry, based on the resemblance of the electronic properties of the atoms involved. In spite of having two approaches, the historical one has been almost abandoned and the quantum chemical oversimplified to free atoms, which are of little interest for chemistry. Here we show that a mathematical and computational historical approach yields well-known chemical similarities of chemical elements when studied through binary compounds and their stoichiometries; these similarities are also in agreement with quantum chemistry results for bound atoms. The results come from the analysis of 4,700 binary compounds of 94 chemical elements through the definition of neighbourhoods for every element that were contrasted producing similarity classes. The method detected classes of elements with different patterns on the periodic table, e.g. vertical similarities as in the alkali metals, horizontal ones as in the 4th-row platinum metals and mixed similarities as in the actinoids with some transition metals. We anticipate the methodology here presented to be a starting point for more temporal and even more detailed studies of the periodic table.

IUPAC Periodic Table of The Elements
The 1 Dec 2018 IUPAC (International Union of Pure and Applied Chemistry) Periodic Table of The Elements. For updates to this table click here.
By virtue of its work in relation with the chemical elements, IUPAC can dispense a periodic table that is up-to-date. IUPAC involvement covers various aspects of the table and data that it unveils, and several reports and recommendations, some quite recent, attest of that input. In particular, IUPAC is directly involved in the following:
- establishing the criteria for a new element discovery
- defining the structure of a temporary name and symbol
- assessing claims resulting in the validation and assignation of an element discovery
- coordinating the naming of a new element, involving the research laboratory and allowing for public comments
- setting up precise rules for how to name a new element
- defining Group 1-18 and collective names
- determining which elements belong to Group 3
- regularly reviewing standard atomic weights

First Ionisation Energy to the Standard Form Periodic Table
There is debate amongst the cognoscenti about the 'best' representation of the periodic table, and how this 'best' formulation can be explained by [rationalized by] quantum mechanics (QM).
Many feel that the Janet PT formulation, the 'Left Step', is the ideal QM PT, but this formulation does not show periodicity very well, and there are issues with the placement of H, He, Be which spill over into questions about their placement in the standard form PT (the periodic table used in classrooms and textbooks around the world).
However, it is possible to get to the conventional standard form PT directly from the first ionisation energy data, where the 1st ionisation energy is the energy required to convert a gas phase atom (M) into its gas phase positive ion plus electron.
M(g) → M+(g) + e–
The process involves:
- taking the 1st ionisation data plot for the elements H to Xe (Z = 1 to 36)
- rotate 90° clockwise and stretch
- move the atoms horizontally into columns
Note that a similar logic can be applied to atomic radius and electronegativity data.
However, there are issues about the measurement of atomic radius, because atoms are 'soft at their edges', and gas phase atomic radius is not precisely defined. And, electronegativity is a derived parameter.

Hoyau's Periodic Table Formulations
From Davy Hoyau in France, a selection of periodic table formulations. Davy writes:
"I can explain how i came up to this solution, to better represent graphically the mathematics of the nature. The great advantage of that solution is to make visible how important are the subrings, and not the rings, of the electronics layers. That's why we can call this representation "the table of subrings".
"They seem to be responsible of element chemistry. However, most of time the atom is represented with the full layer, of 2, 8, 18, 32 available positions for determined quanta of energy. But the most important thing is to see how strange is the table when we only have to count the additional electrons needed to finish to fill the layers, following this suit ; 2, 6, 10, 14 (because 2+6=8, 8+10=18, and 18+14=32).
"The traditional representation make easier to follow, vertically, the type of element. For example, follow the column of copper, silver, gold & roentgenium. They have the most conductivity elements of their subrings.
"Also we can follow the column of the noble gases. And that is a surprise to find a noble gas at the only first subring of the first ring, but at all the second subrings of all other rings. That let imagine an extremely innovative way to fill the free locations of energy, not simple by adding marbles on a sequence of positions, but more like a type of musical chair game (i cant be more precise actually). That show how are possibles the "errors" of filling that this 3D representation can't show, if you watch attentively the known data on the filled layers. For example, vanadium 23 is 2-8-11-2, and chrome 24 is 2-8-13-1."

Telluric Remix
Philip Stewart writes:
The Telluric Helix (La Vis Tellurique) was the first graphic representation of the periodic system of the elements, conceived as a spiral wound round a cylinder. It was designed in 1862 by Alexandre-Émile Béguyer de Chancourtois, a French mineralogist. 'Telluric' is from Latin tellus, earth, recalling the 'earths', oxides, in which many elements had been discovered.
My 'Telluric Remix' is a return to the cylinder. It combines ideas from Charles Janet (8, not 7, periods, ending with ns2, defined by a constant sum of the first two quantum numbers, n and l), Edward Mazurs (all members of each electron shell in the same row) and Valery Tsimmerman, (a half square per element).
- The Telluric Remix is topologically the same as my 'Janet Rajeuni' and 'Chemosphere': it maintains the continuous sequence of atomic numbers with the help of arrows, which cascade down, displaying graphically the Janet [Madelung] rule for the order of subshell filling.
- I have placed the s block in the centre to emphasise its pivotal nature and so that there is no question of whether it belongs on the left or on the right. Every shell (Arabic numeral) and every period (Roman numeral) ends with ns2, but the ns electrons combine with f, d or p electrons of elements in the succeeding period to make their valence shells, until ns2+np6, which forms a noble gas. Helium, He, is also noble with a complete n=1 shell and no 1p6.
- Noble gases are marked G. Groups are numbered sequentially within each block, and in general the xth member of the series has x electrons in the subshell. Exceptions are shown by a small d (or two) in the corner, signifying that a d electron replaces an s electron in the d block or an f electron in the f block (note also p in Lr). This makes it easy to determine the electronic structure of each element.

Puddenphatt & Monagham Periodic Table
Jeries Rihani's version of R. J. Puddenphatt and P. K. Monaghan, published in1989, but is not an exact copy. The differences are as follows:
- It adds color: YELLOW for the s-block, GREEN for the p-block, BLUE for the d-block and PURPLE for the f-block.
- It avoids being congested since it excludes the electronic configurations of the elements.
- It is updated and includes the atomic numbers 119 and 120.
- It shows that it is symmetrical around the vertical axis.
- The f-block, like all the other blocks, ends with even atomic numbers.

Janet's Left-Step with Ground Level Microstates
By Valery Tsimmerman, who writes:
Janet's LST with ground level microstate information and total spin graph shown for each group of elements. The top line represents number of electrons in open sub-shells (with exception of six anomalous elements). Information shows physical (spectroscopic) basis of the groups.
The zigzag line on top is a graphic representation of Hund's rule showing the total inherent spins of atoms and the total spin of Cu is 1/2, same as for Ag and Au. When it comes to ground level atomic microstates and Hund's rule Cu is not anomalous (2S1/2), despite its anomalous electron configuration.
The diagram represents Hund's Rule that states that "the lowest energy atomic state is the one that maximizes the total spin quantum number for the electrons in the open subshell" (Wikipedia). Y-axis is the total spin and x-axis is number of electrons in open shells (with exception of six anomalous elements).
First, I would like to make couple of general comments. When discussing periodicity, they typically talk about chemical properties and electron configurations/differentiating electrons, etc, but those are not specific enough. For each electron configuration there are multiple microstates. For example, for single electron configuration of carbon there are over 30 microstates and only one of them corresponds to ground level. So, microstates express combined physical/spectroscopic properties of whole atoms and, the most important, combined properties of electrons located in open subshells.
Now, look at ground level term symbols in each group. I see amazing consistency, especially in the main groups. It tells me that groups are not only chemical, but physical!
Looking at periods one can see that all periods in s, p & d blocks begin with elements that have multiplicity M=2 and end with M=1. This is also true for f-block if it starts with La and Ac and ends with Yb and No. This puts Lu and Lr firmly in group 3. Placing La and Ac in group three ruins spectroscopic consistency.

Archetypes of Periodic Law
Archetypes of Periodic Law by Dmitry Weise, read more on the website.
One of the creators of quantum mechanics Wolfgang Ernst Pauli wrote in his work The Influence of Archetypal Ideas on the Scientific Theories of Kepler (1948):
"The process of understanding nature as well as the happiness that man feels in understanding – that is, in the conscious realization or new knowledge – seems thus to be based on a correspondence, a 'matching' of inner images pre-existent in the human psyche with external objects and their behavior. This interpretation of scientific knowledge, of course, goes back to Plato and is, as we shall see, advocated very clearly by Kepler. These primary images, which the soul can perceive with the aid of an innate 'instinct', are called by Kepler archetypal. Their agreement with the 'primordial images' or archetypes introduced into modern psychology by C. G. Jung and functioning as 'instincts of imagination' is very extensive. A true spiritual descendant of the Pythagoreans, he attached the utmost importance to geometric claiming that its theorems 'have been in the spirit of God since eternity'. His basic principle was: 'Geometria est archetypus pulchritudinis mundi' (Geometry is the archetype of the beauty of the world)."
Dmitry writes:
"The key archetype, in our opinion, is the concept of the square and its gnomon. This is due to the well-known fact that the electron filled shell contains 2n2 electrons, and the number of electrons on the subshell is twice the odd number; the gnomon of the square. Triangle, tetrahedron, square pyramid, octahedron, pyramid-like figures composed of square layers are also considered. The methodical concept for these constructions is the figurate numbers, actively studied by the Pythagoreans. The tables of the periodic law built on the motifs of ancient folk and modern ornaments take a special place. They include not only geometric archetypes, but also magic-symbolic, cultural and religious archetypes of the collective unconscious. Note that the periodic law table, built on the basis of the Native American ornament, surpasses the modern Mendeleev table in the parameter reflecting quantum numbers in its structure."

Physical Origin of Chemical Periodicities in the System of Elements
From de Gruyter: Physical origin of chemical periodicities in the system of elements, Chang-Su Cao, Han-Shi Hu, Jun Li* and W. H. Eugen Schwarz*, Pure Appl. Chem. 2019; 91(12).
Published Online: 2019-11-30 | DOI: https://doi.org/10.1515/pac-2019-0901 (open access)
Abstract:
The Periodic Law, one of the great discoveries in human history, is magnificent in the art of chemistry. Different arrangements of chemical elements in differently shaped Periodic Tables serve for different purposes. "Can this Periodic Table be derived from quantum chemistry or physics?" can only be answered positively, if the internal structure of the Periodic Table is explicitly connected to facts and data from chemistry.
Quantum chemical rationalization of such a Periodic Tables is achieved by explaining the details of energies and radii of atomic core and valence orbitals in the leading electron configurations of chemically bonded atoms. The coarse horizontal pseudo-periodicity in seven rows of 2, 8, 8, 18, 18, 32, 32 members is triggered by the low energy of and large gap above the 1s and nsp valence shells (2 ≤ n ≤ 6 !). The pseudo-periodicity, in particular the wavy variation of the elemental properties in the four longer rows, is due to the different behaviors of the s and p vs. d and f pairs of atomic valence shells along the ordered array of elements. The so-called secondary or vertical periodicity is related to pseudo-periodic changes of the atomic core shells.
The Periodic Law of the naturally given System of Elements describes the trends of the many chemical properties displayed inside the Chemical Periodic Tables. While the general physical laws of quantum mechanics form a simple network, their application to the unlimited field of chemical materials under ambient 'human' conditions results in a complex and somewhat accidental structure inside the Table that fits to some more or less symmetric outer shape. Periodic Tables designed after some creative concept for the overall appearance are of interest in non-chemical fields of wisdom and art.

Leach's Empirical Periodic Table
The common/conventional/standard 'medium form' periodic table is based on the 1945 Seaborg formulation, and it is interesting to explore where this formulation – and its 1939 predecessor – come from. (Interestingly, the Werner formulation of 1905 is not cited as a source and there are no other similar formulations in the (this) Periodic Table Database.)
However, it is possible to get to the common/conventional/standard periodic table directly from two readily available data-sets: (1) first ionisation energy of the gas phase atoms, and (2) atomic radius.
The procedure involved plotting the data, rotating 90°, squeezing vertically and smoothing. The points need a little tidying up, and then they can be mapped directly onto the Seaborg formulation periodic table.
The only element which does no obviously 'line-up' with the periodic table is hydrogen, but many modern periodic tables have H floating as it is not obvious if it should be considered to be a Group 1 alkali metal or a Group 17 halogen.
Note:
There are advantages and disadvantages to each data set. The 1st ionisation energy data from NIST is known with up to seven significant figures of precision, but the data jumps about at times due to the presence of the s & p-orbitals, which appears to make the data a little noisy. (Actually, this 'noise' is embedded information about the electronic structure of the atoms.) The atomic radius gives smoother data, but as gas phase atoms do not have hard edges calculated (Clementi 1967) rather than experimental values, must be used.

UCLA Periodic Table (Proposed)
Eric Scerri writes:
During an office hour here at UCLA with a couple of students – Annelise Gazale & Chidinma Onyeonwu – we came up with a 'new periodic table'.
The basis of it is related to a point you frequently make against the Left Step formulation, namely that it messes up trends in atomic radius etc.
So how about this: Traditionally on the right side of the table elements become less reactive as we move down, but on the right side of the table elements become more reactive as we move down. Consequently, the noble gases are anomalous in the way they usually sit since they become more reactive as we move down the table.
Ergo: Move the noble gases to the left edge of the table. (Yes, this has been done before of course but not for this reason.)

"Can quantum ideas explain chemistry's greatest icon? Simplistic assumptions about the periodic table lead us astray.
"Such has been the scientific and cultural impact of Dmitri Mendeleev's periodic table of the elements that many people assume it is essentially complete. [But] in its 150th year, can researchers simply raise a toast to the table's many dividends, and occasionally incorporate another heavy synthetic element?
"No – this invaluable compilation is still not settled. The placements of certain elements, even hydrogen and helium, are debated."

Telluric Remix in Colour
Philip Stewart writes (this is the same text that accompanies the 2018 B/W version):
The Telluric Helix (La Vis Tellurique) was the first graphic representation of the periodic system of the elements, conceived as a spiral wound round a cylinder. It was designed in 1862 by Alexandre-Émile Béguyer de Chancourtois, a French mineralogist. 'Telluric' is from Latin tellus, earth, recalling the 'earths', oxides, in which many elements had been discovered.
My 'Telluric Remix' is a return to the cylinder. It combines ideas from Charles Janet (8, not 7, periods, ending with ns2, defined by a constant sum of the first two quantum numbers, n and l), Edward Mazurs (all members of each electron shell in the same row) and Valery Tsimmerman, (a half square per element).
- The Telluric Remix is topologically the same as my 'Janet Rajeuni' and 'Chemosphere': it maintains the continuous sequence of atomic numbers with the help of arrows, which cascade down, displaying graphically the Janet [Madelung] rule for the order of subshell filling.
- I have placed the s block in the centre to emphasise its pivotal nature and so that there is no question of whether it belongs on the left or on the right. Every shell (Arabic numeral) and every period (Roman numeral) ends with ns2, but the ns electrons combine with f, d or p electrons of elements in the succeeding period to make their valence shells, until ns2+np6, which forms a noble gas. Helium, He, is also noble with a complete n=1 shell and no 1p6.
- Noble gases are marked G. Groups are numbered sequentially within each block, and in general the xth member of the series has x electrons in the subshell. Exceptions are shown by a small d (or two) in the corner, signifying that a d electron replaces an s electron in the d block or an f electron in the f block (note also p in Lr). This makes it easy to determine the electronic structure of each element.

Grainger's Elemental Periodicity with "Concentric Spheres Intersecting Orthogonal Planes" Formulation
From Tony Grainger, an Elemental Periodicity formulation with concentric spheres intersecting orthogonal planes.
Tony writes:
"I hand sketched this periodic table about a decade ago and placed it on my cubicle window at UTAS, with minimal comments from work mates. It bears some similarity to other formulations in the database, especially when cut along the left axis and laid flat. The concept of all elements of a period being aligned along orthogonal planes cutting a sphere was inherent in the original sketch. When I began using SVG about five years ago I realised I could draw this as a real projection of the 3D model. It was on the back burner, until I found the original sketch during a tidy up."
There are two images of this 3D formulation: an "inside_corner_below/outside_corner_above" (top image) and an "outside_corner_below/inside_corner_above" lower image.
- The "inside corner below" is like looking at the junction of a floor and two walls in the corner of a room.
- The "outside corner above" is like looking up at the underside of an overhanging corner of a building.
- The "outside corner below" is like looking down on the corner of a large box.
- The "inside corner above" is like looking at the junction of walls and a ceiling in a room.

Poliakoff's Inverted Periodic Table
From Nature Chemistry. Martyn Poliakoff et al write:
"The inverted periodic table is obtained by rotating the conventional one by 180° about a horizontal axis.
"a, The lighter elements are now at the bottom and the filling of the electron shells occurs upwards. Just like the traditional representation, many properties (for example, atomic number) increase across the table as one proceeds from left to right, but in the inverted version, the same properties now increase as one moves from the bottom to the top, which is the way that most graphs are plotted. Also like the conventional table, the lanthanides and actinides still sit uncomfortably in an isolated block.
"b, In principle, this could be overcome by inverting the 'long form' of the table but, like the conventional long form, it is probably too elongated to be very useful to most chemists."

Chemical Bonds, Periodic Table of
The Max Planck Society (M-P-G, Max-Planck-Gesellschaft) has an article about the hidden structure of the periodic system.
Guillermo Restrepo, MPI for Mathematics in the Sciences:
"A periodic table of chemical bonds: Each of the 94 circles with chemical element symbols represents the bond that the respective element forms with an organic residue. The bonds are ordered according to how strongly they are polarized. Where there is a direct arrow connection, the order is clear: Bonds of hydrogen, for example, are more polarized than bonds of boron, phosphorus, and palladium. The same applies to rubidium in comparison to caesium, which has particularly low polarized bonds and is therefore at the bottom of the new periodic table. If there is no direct arrow between two elements, they may still be comparable – if there is a chain of arrows between them. For example, the bonds of oxygen are more polarized than the bonds of bromine. Bonds represented by the same colour have the same binding behaviour and belong to one of the 44 classes.":

Using a suitable criterion, the objects can be classified into groups (dashed lines) in which the red arrows create a sub-order":

Group 3 of The Periodic Table
There are several ways in which the 'common/modern medium form' periodic table are shown with respect to the Group 3 elements and how the f-block is shown. Indeed, there is even some dispute about which elements constitute Group 3. There are three general approaches to showing Group 3:
- Sc, Y, La, Ac
- Sc, Y than a gap for the lanthanides & a gap for the actinides
- Sc, Y, Lu, Lr
(See Scerri's take and Thyssen's view on this matter.)
So, which one of the three options is 'better'?
The general feeling amongst the knowledgeable is that leaving a gap is not an option, so it comes down to:
Sc, Y, La, Ac vs. Sc, Y, Lu, Lr
René Vernon has looked as the properties of the potential Group 3 elements, including: densities, 1st ionisation energies, ionic radii, 3rd ionisation energies, melting points & electron affinity:
Figure 1 shows that a Z plot of the density values for Sc, Y, La, Lu Ac and Lr follows a smooth trendline.
Figure 2 shows that a Z plot of the first ionization energy values follows a smooth trendline.
Figure 3 shows that a Z plot of the 6-coordinate ionic radii for the subject elements bifurcates after Y into an -La-Ac tranche (R2 = 0.99) and a -Lu-Lr branch (0.61). The trendline for -La-Ac is smoother.
Figure 4 shows a Z plot of 3rd ionisation energy values bifurcating after Y into a -Lu-Lr tranche (R2 = 0.83) and a -La-Ac branch (0.98). The trendline for -La-Ac is smoother.
Figure 5 shows that a Z plot of the melting points bifurcates after Y into an -Lu-Lr (R2 = 0.72) tranche and a -La-Ac (0.71) branch. While the fit values for the two options are comparable, -Lu-Lr is preferred since Y and La show a greater departure from trend.
Figure 6 has a Z plot of electron affinity values bifurcating after Y into an -La-Ac tranche (R2 = 0.85) and a -Lu-Lr branch (0.99).[iii] The trendline supports Lu-Lr. The trend-lines by themselves are inconclusive: two show no difference; two support -La-Ac; two support -Lu-Lr.
Upon reviewing the data, René's comment is that: "The net result is that the two options seem inseparable" and he proposes that IUPAC adopt the following periodic table numbering system:

Colburn's 2019 Periodic Table of The Elements
Justin Lee Colburn writes:
"What is unique to my Periodic Table is the fact that any Elements Electron Spin can be identified for Orbital Diagrams using a technique I have called 'Element Shifting'.
"Elements with an Up spin Valence Electron are shifted up and Elements with a down spin are shifted down. Also, the Hund's rule Exceptions are Highlighted in the Transition Metals so their orbital diagrams can also be identified easily.
"In addition, an accurate numbering system can be applied to all the elements with Helium placed in Group 2 instead of Group 18. I believe that quantitative data should take priority when giving elements their position, but this system is meant to be dynamic rather than static. In my Periodic Table System, (1-8) corresponds to Valence Electrons in the s and p orbitals and then the 9-18 and 19-32 corresponds to core electron in d and f orbitals .
I believe that it is important to begin by showing students the first 20 Elements FIRST because they all add Outer Valence Electrons which makes the Periodic Table logic easy to follow. Also explaining that Hydrogen and Helium are anomalies with more than one logical position, can really help clear up confusion for new students.
"After element 20, the Transition Elements such as scandium 21 begin adding core electrons in the d orbital the current standard (1-18) numbering system does not reflect this. One of the reasons why I prefer keeping the s and p block elements on the outside of the table and the f and d block elements on the inside is because of how they add electrons to their orbitals.
"I have been developing a curriculum based on this system that I believe will help students learn and understand the logic and trends of The Periodic Table more efficiently than the standard. Rather than memorizing Element information, Students will truly be able to follow the logic based on the location of the Elements, simple counting and using the numbering system."

Elements & Anti-Elements (Atom-to-Adam)
"The underlying order of the Atoms and asking the question of Intelligent Design has inspired my work. I have developed a new and improved Periodic Table of Elements that restores the Lanthanides and Actinides in their proper positions while also applying a complete and accurate numbering system. (1-8) numbering in s and p blocks correspond to Valence Electrons with (9-18) and (19-32) corresponding to core Electrons in the d and f block Elements.
"I have also inverted the Periodic Table of Elements which reflects the "missing" Anti Matter of our Universe. Unique to my Periodic Table of Elements is the ability to easily identify any Elements Electron Spin for Orbital Diagrams by shifting Elements up or down. Lastly I have highlighted some of the AUFBAU Exceptions or Electron Configuration anomalies in the transition metals. Interestingly, standing the Periodic Tables upright resembles the image of human beings, hence the title of my project, from Atom to Adam."

Vernon's Oxidation Number Periodic Table
René Vernon's periodic table showing oxidation number trends.
René writes:
- This table is based on two tables by Fernelius (1986), one of which is a portrait version of Bohr's 1922 table, and the second of which is a conventional table highlighting oxidation number trends in groups 4 to 10, and most of the p-block. Ref. Fernelius WC , 'Some reflections on the periodic table and its use', Journal of Chemical Education, vol. 63, no. 3, pp. 263–266 (1986).
- In my table, the transition metals are in groups 4 to 11. As per Mark's Leach's email: "...It's the 'incomplete d-subshell' that gives rise to properties such as: variable oxidation state, catalytic behaviour, d-orbital splitting and [thus] coloured ions/compounds."
- I've included oxidation number details for some elements. I've tried a different way of showing the composition of a bifurcated group 3, which is more in keeping with Bohr's table.
- The horizontal bar of the "T" is for Sc → Ti; the downward bar is for Y → Lu-Lr.
- Thus, Group 3 as Sc-Y-Lu-Lr could be called group 3T.
- La-Ac and Lu-Lr are duplicated in a greyed-out style to make it clearer where the lanthanides and actinides fit into the main body of the table.
- The inner transition metals are clearly delineated. Analogously to the transition metals they're all capable of forming ions with incomplete f sub-shells.
- The early actinides resemble the transition metals.

"Elements with proton magic-number nuclei are arranged on the right-most column, just like the noble-gas elements in the familiar atomic periodic table.
"The periodic properties of the nuclei, such as their stability and deformation from spherical shape, are illustrated in the table. Interestingly, there is a fortuitous resemblance in the alignments of the elements: a set of the elements with the magic number nuclei 50(Sn), 82(Pb) and Fl(114) also appears as the group 14 elements in the atomic periodic table. Thanks to this coincidence, there are similarities in the alignments beyond 41(Nb) (e.g., Nb-Ta-Db or La-Ac in the same columns) in both the nuclear and atomic periodic tables of the elements.

Nawa Version of Maeno's Nuclear Periodic Table
Nagayasu Nawa - "A Japanese school teacher and periodic table designer" - has developed two versons of the Hagino-Maeno Nuclear Periodic Table.
Nawa writes:
"I have made two Nuclear PTs based on Hagino-Maeno (2020). I have tried to express the Nuclear PT visually by using symbols such as '〇','◇','☓' or small '〇' or '●' in a binary way so that people with colour blindness could understand it. And the other have been with the ' QUAD electronic data."

Vernon's Periodic Table showing the Idealized Solid-State Electron Configurations of the Elements
René Vernon writes:
"I've attached a periodic table showing the solid-state electron configurations of the elements. Among other things, it provides a first order explanation as to why elements such as Ln (etc.) like the +3 oxidation state.
"The table includes two versions of the f-block, the first starting with La-Ac; the second with Ce-Th. The table with the first f-block version has 24 anomalies [with respect to Madelung's rule]; the table with the second f-block version has 10 anomalies.
"In the case of the Sc-Y-La-Ac form, I wonder if such a solid-state table is more relevant these days than a table based on gas phase configurations, which has about 20 anomalous configurations.
"Partly we use gas phase configurations since, as Eric Scerri mentioned to me elsewhere, configurations were first obtained (~100 years ago?) from spectroscopy, and this field primarily deals with gas phase atoms. That said, are gas phase configurations still so relevant these days – for this purpose – given the importance of solid-state physics?
"I've never been able to find a periodic table of solid-state electron configurations. Perhaps that has something to do with it? Then again, surely I'm not the first person to have drawn one of these?"

Correlation of Electron Affinity (F) with Elemental Orbital Radii (rorb)
From Jour. Fac. Sci., Hokkaido Univ., Ser. IV. vol. 22, no. 2, Aug., 1987, pp. 357-385, The Connection Between the Properties of Elements and Compounds; Mineralogical-Crystallochemical Classification of Elements by Alexander A. Godovikov & Yu Hariya and expanded by René Vernon who writes.
René Vernon writes:
I was delighted to read about two properties that account for nearly everything seen in the periodic table.
Two properties
While researching double periodicity, I happened upon an obscure article, which simply correlates electron affinity with orbital radius, and in so doing reproduces the broad contours of the periodic table. Having never thought much about the value or significance of EA, and its absence of easily discernible trends, I was suitably astonished. The authors left out the Ln and An and stopped at Bi. They were sitting on a gold mine but provided no further analysis.Development
I added the data up to Lr, updated the EA values, and have redrawn their graph. It is a thing of beauty and wonderment in its simplest sufficient complexity and its return on investment. I've appended 39 observations, covering all 103 elements.
Observations
- Very good correspondence with natural categories
- Largely linear trends seen along main groups; two switchbacks seen in group 13; also falloffs (6p sub-shell) seen in groups 14-17
- First row anomalies seen for Li (in amphoteric territory), Be (ditto), C (misaligned), N (in noble gas territory), O (misaligned), F (ditto) and He (ditto)
- For group 13, the whole group is anomalous, no doubt due to the scandide contraction impacting Ga and the double whammy of the lanthanide and 5d contraction impacting Tl
- Nitrogen was called a noble gas before the discovery of the real noble gases and appropriately enough falls into that territory
- Rn is metallic enough to show cationic behaviour and falls just outside of noble gas territory
- F and O are the most corrosive of the corrosive nonmetals
- The rest of the corrosive nonmetals (Cl, Br and I) are nicely distributed, across the border from F
- The rest of the simple and complex anions, funnily enough, comprise the intermediate nonmetals
- The metalloids are nicely aligned; Ge falls a little outside of the metalloid line, being still occasionally referred to as a metal; Sb, being the most metallic of the metalloids falls outside the border; At is inside; Po is just outside
- Pd is located among the nonmetals due to its absence of 5s electrons; see here
- The proximity of H to Pd is astonishing given the latter's capacity to adsorb the former
- The post-transition metals (PTM) form an "archipelago of amphoterism" bounded by transition metals: Ni and C to the west; Fe and Re to the south; V, Tc and W to the east; noble metals to the north
- Curiously, Zn, Cd, and Hg are collocated with Be, and distant from the PTM and the TM proper (aside from Mn)
- Zn is shown as amphoteric, which it is. Cd is shown as cationic but is not too far away from amphoteric territory; it does show amphoterism, reluctantly; Hg is shown as amphoteric which is the case, weakly, for HgO, as is the congener sulfide HgS, which forms anionic thiomercurates (such as Na2HgS2 and BaHgS3) in strongly basic solutions
- The ostensibly noble metals are nicely delineated; Ag is anomalous given its greater reactivity; Cu, as a coinage metal, is a little further away
- The proximity of Au and Pt to the halogen line is remarkable given the former's capacity to form monovalent anions
- The ferromagnetic metals (Fe-Co-Ni) form a nice line
- The TM from groups 4-12 form switchback patterns e.g. Ti-Zr and the switchback to Hf
- The refractory metals, Nb, Ta, Mo, W and Re are in a wedge formation
- Tc is the central element of the periodic table in terms of mean radius and EA values; V is close, Cr is a little further away
- Ti is just inside the basic cation line; while Ti(IV) is amphoteric, Ti3+ is ionic
- Sc-Y-La shows a main group pattern up to La, when there is a switchback to Ac
- Sc-Y-Lu-Lr shows a TM switch back pattern
- La, and to lesser extent Ce are rather separated from the rest of the Ln, consistent with Restrepo and here.
- Sc and Lu are close to the amphoteric territory and are both in fact, weakly amphoteric
- The post-cerium Ln and An (but for Th) all fall within basic cation territory
- EA values for the An are estimates and need to be treated with due caution
- The light actinides (Th to Cm) occupy a tight locus, with the exception of Th, where the 5f collapse is thought to occur, and Pu, which sits on the border of 5f delocalisation and localisation
- While the light actinides U to Cm are shown as being cationic they are all known in amphoteric forms
- The heavy actinides, Bk to Lr, are widely dispersed
- All the Ln, bar Tm, are located within close proximity of the light An locus; Tm is the least abundant stable Ln
- The gap between La and Ce, and rest of the Ln is consistent with Restrepo's findings and here
- Nobelium in this edition of the chart falls off the bottom, having a radius 1.58 (cf Es) and an EA of -2.33
- There is an extraordinary alignment between He and the Group 2 metals
- Magnesium is on the cationic-amphoteric boundary; some of its compounds show appreciable covalent character
- Li, being the least basic of the alkali metals, is located just outside the alkalic zone; Li compounds are known for their covalent properties
- The reversal of the positions of Fr and Cs is consistent with Cs being the most electronegative metal
- A similar, weaker pattern is seen with Ba and Ra.
Conclusion
So there it is, just two properties account for nearly everything.

Vernon's Constellation of Electronegativity
René Vernon has created a "Constellation of Electronegativity" by plotting Electronegativity against Elemental Orbital Radii (rorb)
Observations on the EN plot:
- The results are similar to the orbital radii x EA plot, although not quite as clear, including being more crowded
- Very good correspondence with natural categories
- Largely linear trends seen along groups 1-2, 17 and 15-18 (Ne-Rn)
- First row anomaly seen for He (or maybe not since it lines up with the rest of group 2)
- For group 13, the whole group is anomalous
- For group 14 , the whole group is anomalous no doubt due to the scandide contraction impacting Ge and the double whammy of the lanthanide and 5d contraction impacting Pb
- F and O are the most corrosive of the corrosive nonmetals
- The rest of the corrosive nonmetals (Cl, Br and I) are nicely aligned with F
- The intermediate nonmetals (IM) occupy a trapezium
- Iodine almost falls into the IM trapezium
- The metalloids occupy a diamond, along with Hg; Po is just inside; At a little outside
- Rn is metallic enough to show cationic behaviour and falls into the metalloid diamond
- Pd is located among the nonmetals
- The proximity of H to Pd is again (coincidentally?) curious given the latter's capacity to adsorb the former
- The post-transition metals occupy a narrow strip overlapping the base of the refractory metal parallelogram
- Curiously, Zn, Cd, and Hg (a bit stand-off-ish) are collocated with Be, and relatively distant from the PTM and the TM proper
- The ostensibly noble metals occupy an oval; curiously, W is found here; Ag is anomalous given its greater reactivity; Cu, as a coinage metal, is a little further away
- Au and Pt are nearest to the halogen line
- The ferromagnetic metals (Fe-Co-Ni) are colocated
- The refractory metals, Nb, Ta, Mo, W and Re are in a parallelogram, along with Cr and V; Tc is included here too
- Indium is the central element of the periodic table in terms of mean orbital radius and EN; Tc is next as per the EA chart
- The reversal of He compared to the rest of the NG reflects #24
- All of the Ln and An fall into an oval of basicity, bar Lr
- The reversal of the positions of Fr and Cs is consistent with Cs being the most electronegative metal
- A similar, weaker pattern is seen with Ba and Ra.

Jodogne's Periodic Table of The Elements
Dr.Ir.Jodogne Jean Claude writes:
"I have the pleasure to send to you my paper on the PT which appears in Chimie Nouvelle 133 of the Soc.Royale de Chimie. However for the moment it is in French. The paper contains and explains the ultimate evolution of my preceding PT but it is the most scientifically based. Pedagogically, I believe it is interesting and easy. As you will see it keeps most of the chemical usual properties of the traditional one."

artlebedev's 100,000 Permutation Periodic Table of The Elements
Moscow-based design company Art. Lebedev Studio have released a new Periodic Table which can be adapted for any task.
- Since 1869, Mendeleev's periodic law has been widely regarded as one of the most ground-breaking advances in our understanding of the laws of nature. Used around the world in classes, lecture halls, and laboratories, the periodic table helps us to understand the elements that make up our world – and the relationships between them.
- Despite this, people have never been able to agree on which information the perfect table should include. What may be useful in a professional context, for example, would be unbearably complex for a student. On the other hand, showing each element's characteristics in full would make the table almost impossible to navigate. This has always resulted in an awkward compromise between simple and detailed.
- Art. Lebedev Studio made an adaptable table which lets users compare values, reveal patterns, and make their own discoveries. If a student only needs to see the element symbols, they can simply omit the other parameters. If someone wants to find out which country discovered the largest number of elements, they can include the flags of each nation's achievements (spoiler: it's the UK with 24).
- As well as liberating scientists from the limitations of fixed tables, the Studio also focused on improving the table's appearance. Designers came up with a clean, readable typeface which makes each element almost feel like a standalone design. They also made it highly adaptable, allowing users complete control over everything from nomenclature to background and cell colours.
- With over 100 000 permutations, users are sure to find the right table for them – whether they are a lab technician, lecturer, or student.

Lehikoinen's Circular Clock Form
Otto Lehikoinen writes:
"A circular form separating 1s orbital to the center, set it on a wall clock as there are 48 elements of main periods, thus can be used as markers for half hours. Group 4 is centered on noon and group 7 starts the afternoon, to get anions and cations with the same but opposite charge to be beside each other. Thus the noble gases are centered on midnight which is easily remembered by neon (and other noble gas) lights. The minute hand hits the 40 d-block elements giving an accuracy of 1.5 minutes and seconds could be read from lanthanides and actinides."

Vernon's Periodic Treehouse
René Vernon's Periodic Treehouse of the Elements, fearuring the World's longest dividing line between metals and nonmetals.
René writes:
I can't remember what started me off on this one. It may have been Mendeleev's line, as shown on the cover of Bent's 2006 book, New ideas in chemistry from fresh energy for the periodic law.
There are a few things that look somewhat arbitrary, so I may revisit these:
- Ce is known at +4, Pr is known as +5, and I recall seeing some speculation about the possibility of Nd +6. (Pm +7 may be overreach.)
- Tl is lined up under Au even though Tl prefers +1. That said Au is not adverse to +1.
- I stopped at Hs since the limits of SHE chemistry just about runs out there.
- The dividing line between metals and nonmetals is 73 element box sides long.
