Periodic Arch of The Elements
Cynthia K. Whitney of Galilean Electrodynamics writes: "In his paper Explaining the periodic table, and the role of chemical triad, Eric Scerri mentioned the existence of at least four different candidate places for Hydrogen: Group 1 (alkali metals - Lithium, etc.), Group 17 (halogens - Fluorine, etc.), Group 14 (Carbon, etc.), or off the Periodic Table entirely, because it is so odd! The four-fold multiplicity (and maybe more) of candidate places for Hydrogen triggered in me the following thought: the excessive multiplicity of candidate places may have to do with the rectangular nature of the Periodic Tables under consideration there."

Vajra Periodic Table
The Vajra Periodic Table, which can be found at APM Periodic Tables, lays out according to electron orbitals and thus gives insights into the electron structure surrounding the nucleus. The nucleus organizes with different rules and thus a different periodic table is needed to visualize the nuclear bindings:
Pauling Spheron Periodic Table
Linus Pauling was a brilliant physicist who tended to think outside the mainstream. One of his many contributions to science was his spheron model for the nucleus. The word "spheron" does not mean the nucleus is spherical (although it may be), it refers to Pauling's idea that clusters might form in the nucleus. For example, a nucleus may contain a stable helium nucleus within a larger uranium nucleus. Thus, when uranium decays, it releases a helium atom. Other elements, such as oxygen, may also cluster within larger elements. This makes sense since certain atoms like helium and oxygen are more strongly bound than other elements:

Pyykkö's Extended Elements
From an RSC new page: Pekka Pyykkö at the University of Helsinki has used a highly accurate computational model to predict electronic structures and therefore the periodic table positions of elements up to proton number 172 - far beyond the limit of elements that scientists can currently synthesise.
From the paper, A suggested periodic table up to Z = 172, based on Dirac–Fock calculations on atoms and ions:
Harrison Spiral Periodic Table
This spiral, inspired by Stewart's Chemical Galaxy, is based on the modern periodic table with the elements strictly arranged in the increasing order of their atomic number and in accordance with their electron configurations.
The spiral separates the elements into the eight dominant 'A' groups of normal elements, and the eight corresponding 'B' subgroups of transitional and inner transitional elements, which have been incorporated as the inner spiral. The organisation of the elements closely follows H.G. Deming's 1923 Periodic Table where A B numeration was first utilized to correspond the characteristic oxides of the 'B' groups to those of the 'A' groups. The result of this design places Group VIII, the triads Fe, Co, Ni, etc. as a subgroup of Group 0 (or 18 Helium Group) which conflicts with some modern periodic tables, though broadly agrees with Deming's original proposal (VIIIA and VIIIB).
Hydrogen, which generally cannot be considered as part of any group, has been placed with the Fluorine group VII which appears its natural place in the spiral. Common names have been used where practicable to make the table more educational and reader-friendly. Element symbols have been included in the expanded poster of this table.

Upper Limit in Mendeleev's Periodic Table - Element No.155
This book (PDF), by Albert Khazan, represents a result of many-year theoretical research, which manifested hyperbolic law in Mendeleev's Periodic Table.
According to [Khazan's] law, an upper limit (heaviest element) exists in Mendeleev's Table, whose atomic mass is 411.66 and No.155. It is shown that the heaviest element No.155 can be a reference point in nuclear reactions. Due to symmetry of the hyperbolic law, the necessity of the Table of Anti-Elements, consisting of anti-substance, has been predicted. This manifests that the found hyperbolic law is universal, and the Periodic Table is common for elements and anti-elements.

Newlands Revisited – Poster
At the beginning of last year (Meyers, 2009), a IUPAC editorial offered "something old, something new, something borrowed and something blue".
Marks and Marks 2010 (M&M) preserves the old subgroups (Newlands' columns) that were a feature of all short forms, although M&M would then have been described as a 'medium form' (14 groups) in contrast to Mendeleyev's 'short form' (8 groups) or Werner's 'long form' (32 groups). M&M naturally continues the grouping of the lanthanoids/actinoids whose initial four groups were also included in 'short form' tables.
The logic of the arrangement of the s-elements is a new feature. It recognizes the chemical subgroups of hydrogen, viz. the alkali metals and the halogens, and of helium, viz. the alkaline earth metals and the inert gases. It is interesting to note that subgroups differ chemically from each other inversely as the azimuth, i.e. Li:F > Ca:Zn > La:Lu.
The whole idea is, of course, borrowed from Newlands. The group numbers are borrowed from valency but also from electronic structure in that the number of s, p, d, or f subgroups corresponds to the Pauli maximum for each. Finally, the mnemonic reflects that most elementary introduction to chemistry: alkalis turn Litmus blue.
From this start, the p-bloc is red, the transition elements yellow and the "rare earth" elements green, as argued in the M&M paper. The numbering of groups I - XIV is unambiguous, it is less than IUPAC's arbitrary 18 groups, it preserves subgroups and satisfactorily accommodates hydrogen and the lanthanoids/actinoids.
As required by Leigh (2009), this table is clear, simple and brief.

Suggested Periodic Table Up To Z ≤ 172, Based on Dirac–Fock Calculations
A suggested periodic table up to Z ≤ 172, based on Dirac–Fock calculations on atoms and ions
Phys. Chem. Chem. Phys., 2011,13, 161-168
Extended Average Level (EAL) Dirac–Fock calculations on atoms and ions agree with earlier work in that a rough shell-filling order for the elements.
[This new] Periodic Table develops further that of Fricke, Greiner and Waber [Theor. Chim. Acta 1971, 21, 235] by formally assigning the elements 121–164 to (nlj) slots on the basis of the electron configurations of their ions. Simple estimates are made for likely maximum oxidation states, i, of these elements M in their MXi compounds:
"Three-dimensional table of the periodic law can be constructed in the form of a tetrahedron having an inner order. A comparison of the tetrahedron shells and the table of elements shows, that one tetrahedron shell corresponds to 4 periods of the 2D table."
Jess Tauber adds:
"The spheres here also aren't labeled, but I explain how they get labeled in the text accompanying the pic. Each such period (except for s-only, which are obviously simpler) we have a 'switchback' configuration. Like a road going up a mountain back and forth to minimize verticality, or a parachute folded into a pack. There are 8 different ways to do this (4 basic types in 2 chirally opposite mappings). And the original Weise-style non-continuous tetrahedron is just another way to organize half tetrahedra."

In this periodic table we can see that the elements are arranged in a different way. Hydrogen is placed in between (and above) fluorine and lithium. This is because there is an issue on the placement of hydrogen as it has the properties of both alkali metals and halogens.

These 2 transformations lead to the same table, with 7 rows and 32 columns. Blocks p (green), d (light grey), and f (light orange) are preserved.
The 14 terms of the s block (dark orange/red) are splited in "cascads".
Srivaths–Labarca Periodic Table
This is an improved version of the Zigzag Periodic Table (2012). In this new arrangement the main criteria proposed to settle the placement of the elements hydrogen and helium has been taken into account: electronic configurations, the number of electrons needed to fill the outer-shell, chemical behavior, and triads of atomic number.
This is a new categorial criterion recently proposed by Eric Scerri, according to which hydrogen and helium form part of the triads H(1), F(9), Cl(17) and He(2), Ne(10), Ar(18), respectively. Thus, hydrogen preserves its place between alkali metals and halogen while helium is now in between noble gases and alkaline earth elements.
This periodic table allows visualizing easily the relationships of hydrogen and of helium with the different criteria, avoiding drawing lines to see them in contrast to other similar periodic systems.

3D Illustrated Alexander Arrangement of Elements
The design of the 2012 Alexander Arrangement of Elements (AAE) follows the principles of a three-dimensional model developed by Roy Alexander in 1965: a printed representation of element information based on strict adherence to the Periodic Law, with every element data box physically and visually contiguous and continuous within the sequence of atomic numbers in generally accepted element property related columns - "...the periodic table the way it's supposed to be".
This is made possible by wrapping, folding, and joining the printed material and employing the patented p-block downslant of the element data boxes to allow the end element of a period to be adjacent to the first element of the next period.
Several unique features separate it from the previous four versions of the AAE
Designed by Roy Alexander, a science museum exhibit and teaching aid designer, the Adobe Illustrator art for the model was started by Ann Grafelman, and continued by Roy from mid 2011 through November of 2012.
Photos were provided by Theodore Gray, and Element Collection funded the printing and die cutting performed by Strine Printing in York, Pennsylvania. The model kit was first offered at Theo's PeriodicTable.com, then at Roy's AllPeriodicTables.com and the new 3dPeriodicTable.com, which site is dedicated to the 3D Forever Periodic Table only, with add-ons, application suggestions, and descriptions and commentary of all sorts.
Assembly instructions and step photos, as well as a number or completed model color photographs are included with the kit. These were developed with prototype models, and while functional, have been upgraded and accompanied by an assembly video at AlexanderArrangementOfElements.com/3D
Text relating to the abbreviation of the ever increasing number of elements is explained at two places on the 3D AAE illustrated periodic table model kit. One will remain with the model and one is removed at the time of assembly.
That which remains runs under the Actinoids and the d-block elements, where the lab created elements might ordinarily be expected to be found, says:
The lab created elements ordinarily found in this part of a periodic table are not to be found in nature, there can be no photographs of them, so nothing needs to be added to this element photo periodic table - ever - so it will never be obsolete, a Forever Periodic Table.
That which is removed says:
Naturally-occurring elements have been numbered variously, generally between 80 and 96, all for cogent scientific reasons.
For easier teaching and learning, we have included on this periodic table only the 92 elements actually currently existing on Earth and in the remainder of the Universe, and adding Technetium and Promethium, which, although they may have no stable forms, serve to fill what would otherwise be gaps in the sequence.
Not added for practical and educational reasons are 'elements' consisting only of pages and pages of computer data from smashing atoms in particle accelerators. Another reason is that there can be no photographs of them to show, and as a result, your arrangement is complete and never be obsolete - your Forever Periodic Table.
Included with the art of the periodic table on the die cut substrate that makes up the model is some background information about the the history of three dimensional periodic tables.
The first of these is about the discoverer of the concept of arranging the elements in periods suggested by the properties of the elements, de Chancourtois.
The second 3D periodic table information piece (on the rear of the de Chancourtois removable card) are sketches of a number of the 3D periodic tables found on the Chemogenesis website.

Wheelshaped Table of Elements
From Facebook, a Wheelshaped table of elements.
Please note the symmetry of this representation.
As a result, it is possible that element 118 is the very last one in the periodic table. We have the sequence:
2 x 14 (blue)
4 x 10 (brown)
6 x 6 (violet)
8 x 2 (green)
and, logically, neither first nor last factor can be 0 or -2 (they differ in two columns above respectively by 2 and 4). On the other hand, the coherence of the structure requires the existence of two additional elements at the beginning!

Ato Circular Periodic Table by Ramanpreet Singh Jandu
Ramanpreet Singh Jandu writes:
"The present invention relates to a device for the understanding of the periodic table and the structure of the atom together in a better way.
The device consists of seven concentric circular disks rotatable about their centre, wherein the size of the disks increases from the centre to the end like that in the structure of the atom.
Each disk is marked so as to form the sub-blocks and each disk in itself represents the periods of the periodic table.

7 Elemental Chemical Synthesis
The Mystics Guide to Elemental Chemistry, by bzylman at deviantart:
[A] poster is designed to geek out the chemist and the mystic alike. It is a variation on the periodic table of chemical elements that have been rearranged into a circular structure based upon their proton count and chemical family, augmented with the concept of the 7 mystic elements of earth, air, fire, water, metal, wood and void. It was very interesting to work upon once I hit the correct organization of elements that they lined up almost perfectly.
Electronegativity Chart (Leach)
Due to the importance of Pauling's electronegativity scale, as published in The Nature of The Chemical Bond (1960), where electronegativity ranges from Cs 0.7 to F 4.0, all the other electronegativity scales are routinely normalised with respect to Pauling's range.
When the Pauling, Revised Pauling, Mulliken, Sanderson and Allred-Rochow electronegativity scales are plotted together against atomic number, Z, the similarity of the data can be observed. The solid line shows the averaged data:
MCAS Electron Orbital Filling
From Joel M Williams:
"While the periodic table arrangement is usefully interpreted in columns of similar behavior, it is erroneous to imply that the underlying orbitals are all the same for all the elements in the columns of a block. Sub-orbital information has been excluded! From the standpoint of chemistry, the rule of eight would have provided better imagery on which to build an orbital system than was Bohr's orb turned-sphere. A sphere is useless from a chemical standpoint. Hybridization should not have to occur to explain the simplest of molecules. Simplicity would have the electrons occupying orbital spaces that are similar in shape. Only three orbital types are actually needed to describe the electron packing of the elements. Octahedral, square-planar, and pyramidal coordination complexes of the transition elements follow logically without the need to hybridize. This brief paper describes a rational packing of electrons around a nucleus that ends up mimicking the familiar periodic table when compressed to similar behavior."
Modeling the MCAS Way describes this concept of "building blocks" and can be found here.

"A periodic table is constructed from the consideration of periodic properties and the application of the principal components analysis technique. This procedure is useful for objects classification and data reduction and has been used in the field of chemistry for many applications, such as lanthanides, molecules, or conformers classification. From the information given, the whole procedure can be reproduced by any interested reader having a basic background in statistics and with the help of the supplementary material provided. Intermediate calculations are instructive because they quantify several concepts the students know only at a qualitative level.

The chemical elements present in the modern periodic table are arranged in terms of atomic numbers and chemical periodicity. Periodicity arises from quantum mechanical limitations on how many electrons can occupy various shells and subshells of an atom. The shell model of the atom predicts that a maximum of 2, 8, 18, and 32 electrons can occupy the shells identified by the principle quantum numbers n = 1, 2, 3, and 4, respectively. The numbers 2, 8, 18, and 32 are shown in this work to be related to the triangular numbers from mathematical number theory. The relationship to the triangular numbers, in turn, suggests an alternate method for arranging elements in terms of periodicity. The resulting three-dimensional "periodic pyramid" is highly symmetric in shape. Just as is true in the modern periodic table, each layer of the periodic pyramid can be separated into shell and subshell contributions. Examining the pyramid's structure is arguably a pedagogically useful activity for college-level introductory or physical chemistry students, as it provides an opportunity to further ponder the shell model of the atom and the origins of periodicity. The connections to number theory are used to show that the outermost subshell of a given shell contains (2n – 1) orbitals.
Bernard Periodic Spiral
The Bernard Periodic Spiral of the Elements (BPSE), depicts a novel rendition of the Periodic Table that replaces the flat rectangular format with a continuous unidirectional spiral that maintains all the properties of Group and Period formation.
Comparisons may be made with similar models spanning the last three decades of the 20th century (Alexander, 1971; Mazurs, 1974; & Kaufman, 1999).
In the chart form, this new rendition is referred to as the Elliptical Periodic Chart of the Elements. In the three-dimensional form, the model resembles a Christmas tree in shape with the 7 Periods represented as circular platforms situated at various levels with the elements placed appropriately at the outer edges of each of these platforms as a Period builds up. The elements may be represented as spherical objects or flat discs with radii proportionate to atomic radii (or reasonable approximations). Color schemes accentuate the four different Blocks of elements: the s-Block (green), the p-Block (blue, with the exception that the last Group is red signifying the end of a Period), d-Block (orange), and the f-Block (yellow). The grey section, called the Group-Period Interchange, is where the end of a particular Period connects to the beginning of the next Period, and, at the same time, transitions from Group 18 to Group 1.

Among the events commemorating the 75th anniversary of the creation of the School of Treball, the author of this site, B. Navarro, along with J. Semis and J. Gràcia have built a model wooden periodic table.
The table has been divided into 5 areas: representative elements, noble gases, transition elements, rare earths and finally the groups I and II of alkali and alkaline earth together. Each of these areas of the table is made with a different type of wood. The block transition elements is made with oak, ash noble gases, representative elements in cherry, sapele the rare earth and alkali/alcalinoterros beechwood.
The central idea of the model is that each element is represented by a cube of 3 cm edge so that you can see on all sides, from left to right or right to left without losing the order of increasing atomic number or the relative position of the elements:

The Periodic Table with a new double numerical structure, presented here is attempt to find table form which will in some new way represent the periodicity and symmetry of the Elements, with the Periodic System as base. Also this tetrahedral laminar table structure maybe will became a base for developing a new shell structure of atomic nucleus. This new rearrangement of the chemical element is based on mathematical formula which result is simple, length of the periods:

"There is a periodic table, at least in terms of atomic number and electronic configuration, for every positive integer, c >= 2, with a capacity of 20c2 – 21c + 1 elements, where c is the construction index, and c equals one plus the maximum number of electrons per orbital of an atom. The c-construction index and the c-construction-index formulae are unique to this report. The maximum number of potential orbitals per sub-shell of an atom = 3n-1 where n is the index of the s, p, d, and f sub-shells":

ADOMAH Periodic Table Glass Cube
This amazing object is available for sale from Grand Illusions:
A Note by Philip Stewart email@example.com
The cube represents 120 chemical elements etched into a cube of Optical Crystal glass. The s, p, d, and f blocks of the Janet periodic table form four rectangles, which are slices of a regular tetrahedron, parallel with two of its edges and with two faces of the circumscribed cube. All four quantum numbers are made visible in this arrangement. You can see a 2-D version on the Perfect Periodic Table website, click on the "skyscraper" version on the right to see the tetrahedron, and go to Regular Tetrahedron at foot of page for details.
The regular tetrahedron is the only form in which slices are rectangles of different shape and identical perimeter. When each orbital is represented by a square of unit edge, the rectangles representing the blocks all have the same perimeter, which is twice the length of the edges of the tetrahedron (which are of course √2 times the edges of the cube): 18 units = 2(values of n + values of ml).
Valery Tsimmerman, firstname.lastname@example.org, creator of the design, has written to me as follows:
"I just had some thoughts about the Perimeter Rule that is at the basis of the tetrahedral arrangement. Dimensions of the blocks are dictated by number of values of ml and number of values of n. We know that n governs quantization of energy. Recently I learned that quantization of the possible orientations of L with respect to an external magnetic field is often referred to as space quantization. (Serway, Jewett: Physics for Scientists and Engineers. 6th edition. p.1369).
"That is, ml stands for space quantization. Therefore, the Perimeter Rule reflects a direct relationship between energy and space. I think that this could have some significance. The beautiful thing about the Universe is that each type of symmetry is related to some conservation law. Symmetry in time is related to energy. Therefore, n is related to time also, so, in the Perimeter Rule we have relationship between time and space on quantum numerical level. The interesting thing is that ml can be positive and negative, while n can only be positive. Similarly, things can move in space in positive and negative directions, but time has only one direction. There is no negative time, just as there are no negative values of quantum number n."

Zambon's Periodic Table Based on Triads
Alfio Zambon – Universidad Nacional de la Patagonia
In the last decades, the notion of triad has been recovered by Eric Scerri, who suggested it as a possible categorical criterion to represent chemical periodicity. In particular, he reformulates the notion of triad in terms of atomic number instead of atomic weights and, in this way, the value of the intermediate term of the triad is the exact average of the values of the two extremes. The author notes that the attempt of finding new triads is very important since this relation is based exclusively on the atomic number, that is, the only feature of the elements considered as basic substances. In this work, I will follow Scerri's general proposal.

A new way of graphical representation of atoms is developed and presented here. Atoms are recognized as functions of two variables A(r,Θ), where r =2,10,18,36,54,86,118 (given arbitrarily r=1,2,3,4,5,6,7) represents period and Θ representing group, is actually the angle between the groups. A mathematical solution is obtained for Θ having three distinct values of (π /9) radians, (π/18) radians and (π/27) radians which define three super groups satisfying the equation 15(π/27) +10(π/18) +8 (π /9) =2π. 15 groups of two Atoms with a transition zone of (π/27) radians is nominally called Grey Super Group (GSG). 10 groups of which 9 have four Atoms and 1 has two Atoms, also including a transition zone of (π/18) radians, is nominally called Blue Super Group (BSG). 8 groups of which 7 have 6 Atoms and one has 7 Atoms, including a transition zone of (π/9) radians is called Yellow Super Group (YSG). The group with 7 atoms is the so called reference group of Atoms 2, 10, 18,36,54,86 and 118. The GSG has 30 Atoms, the BSG has 38 Atoms and the YSG has 49 Atoms. The Atom 1 is at the centre of the Hub and does not belong to any group or period and has coordinates of (0, 0). Atom 1 having no neutrons is unique.
Metallic Character Table

By Philip Stewart:
Janet Rejuvenated, with acknowledgement to Mazurs and to Valery Tsimmerman for the idea of using one square per orbital and of shifting the blocks so that each row represents one value of n, the principal quantum number.
The main objection people make to Janet is that He is placed at the head of the alkaline earth metals although it behaves as a noble gas. The essential answer is that electronic structure explains behaviour and not vice versa; like Ne (and unlike Ar, Kr, Xe and Rn), He has a complete shell. Similarly H, like C, is half way between a full and an empty shell, unlike the alkali metals and the halogens. I suggest a new argument: nobody finds it strange that the p block has a row of non-metals at its head (and that half its members are non-metals), so why not the s block?

Belikov's Modular Periodic Table of Chemical Elements
"I call this version of the Modular Periodic Table of Chemical Elements. I got the idea for it some time between 2005 and 2007, during the chemistry course at my university, in attempt to rationalize the clumsy common version I was being taught. I showed it to my chemistry teacher, but he didn't seem to be impressed much, so it went into the drawer. Recently I decided to resurrect it and publish somewhere. So I had a look on the web and found your excellent database, with hundreds of versions. After the first shock, I realized that only few are actually similar to my version. These are well known Janet's table and ADOMAH table. So, it appeared to me that the idea to group elements strictly according to filling of their atomic shells is not new. However, the way I have done it is slightly different from the mentioned tables. For example, s,p,d and f blocks of elements are completely autonomous and can be placed wherever desired (hence the name 'Modular'). This reflects the notion that there is little in common in chemical behavior between the elements in different blocks. Also, outer subshell type, energy level and electron count are clearly labeled, so that these parameters can be quickly determined for each element.
"Overall, I think that this version of periodic table allows easier understanding and transition from IUPAC table and could be implemented in school and university textbooks."

Arrangement of Elements 7th Order & Element Sequences
An exploration of some mathematics underlying the periodic table, read the PDF here, by Olivier Joseph.
"May I propose you the following pattern, as the result of a personal study concerning the arrangement of the Elements, including sequences. Based on some hypothesis and as depicted in the enclosed illustrations, the elements are positioned according to a spiral function of atomic number and atomic mass, representation in 2D in a spiral form pattern, or in 3D conical helix model.
"The elements are numbered and placed consecutively along this spiral according to a specific angle, appropriately established between each element, forming a seven arm spiral pattern. With such an angle, specifically defined, a link is established between the various elements of a same group (corresponding to chemical elements with similar properties) and different layers. These latter becoming distributed among each arm of the spiral in a notable arranged way."
Schaeffer's IUPAC Periodic Table Quantum Mechanics Consistent
IUPAC Periodic Table Quantum Mechanics Consistent, Bernard Schaeffer, Journal of Modern Physics, Vol. 5, No. 3, February 24, 2014
Abstract: Most periodic tables of the chemical elements are between 96% and 100% in accord with quantum mechanics. Three elements only do not fit correctly into the official tables, in disagreement with the spherical harmonics and the Pauli exclusion principle. Helium, belonging to the s-block, should be placed beside hydrogen in the s-block instead of the p-block. Lutetium and lawrencium belonging to the d-block of the transition metals should not be in the f-block of the lanthanides or the actinoids. With these slight modifications, the IUPAC table becomes quantum mechanics consistent.
UVS Periodic Table Model of a Klein Bottle Topology
This configuration can topologically suggest the g-block cycle in the 8th period for extended periodic table.
In the Klein bottle topology as illustrated, it is plausible that after the s-block cycle in the 8th periodical cycle, the topological path continues to spiral around the outer f-block cycle to harmonically form 14 elements.
And then subjected to the spiral Möbius strip topological twist, it could resonate to form 4 more elements in the anti-cyclonic path around 17th, 18th, 1st, and 2nd angular phases of the anti-cyclonic core; this would render the 18 elemental positions for the hypothetical g-block cycle in the entire half-integral anti-cyclonic cycle of the Klein bottle topology.
Hypothetically, the topological path then moves into the cyclonic cycle, and harmonically forms its d-block and p-block cycles with 16 elemental positions to complete the 8th periodical cycle with a total of 36 elements.

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:-
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.

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
"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."

Clock Prism Periodic Table, Braille Version
From the prolific Nagayasu Nawa, a Braille version of the Clock Prism periodic table:
P J Stewart, a good friend of the periodic table database, has mapped a PT onto a sphere.
PJS writes: "It is Janet Rajeuni 2014 wrapped round a sphere, going back to Mazurs 1965, and Tsimmerman 2006. Arabic numerals indicate shells (values of principal quantum number); Roman numerals indicate periods."
Moran's Periodic Spiral (Updated)
Jeff Moran has updated his 1999 Periodic Spiral.

Jeff says: I offer the attached spiral formulation as a way of expressing the relationships of the f and d blocs to group 3:
- La and Ac are assigned to the Ln and An series, respectively
- The f block series is within, though apart from, the d block
- The group 3-ish relationship of Ln and An to Sc (and, by extension, to Y) is implied
- The group 3 status of Lu and Lr is explicit
Elements Known and now Named in the Year 2017

Kurushkin's Spiral Periodic Table
Mikhail Kurushkin has a way of constructing the standard long form periodic table from the Janet Left-Step formulation.
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":
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:
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."
Davy has also provided some links to his ideas on the web:

Scerri's Reverse Engineered Version of Mendeleev's Eight Column Table
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).

Sistema Peridico Binodico
By Julio Antonio Gutiérrez Samanez, who writes:
"Sistema Periodico Binodico. Nuevo Paradigma Matematizado. I have followed the work of the wise Mendeleev, of Emil de Chancourtois, of Charles Janet; inspired by the work of my countryman Dr. Oswaldo Baca Mendoza. It is in Spanish but soon I will have the English version."
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.
Puddephatt and Monaghan say "their table is after Philips and Williams":

Periodical System (Binodic Form): a new mathematical paradigm
By Julio Antonio Gutiérrez Samanez, who writes:
"System devised and prepared by the Peruvian chemical engineer, Julio Antonio Gutiérrez Samanez, deals with a new conception of Mendeleev's Law as a mathematical function and a new description of the process of forming the series of chemical elements according to mathematical laws and dialectical processes of changes quantitative and qualitative under a dynamic spiral architecture in 3D, which is postulated as a new scientific paradigm."
Ziaei's Circular Periodic Table
Minoo Ziaei writes:
"My father, Manouchehr Ziaei, has an interesting design of the periodic table, which I helped him draw using AutoCAD. He is very keen in introducing [this formulation] to potential interested viewers, he was recommended to visit [the Chemogenesis Database of Periodic Tables] website."
