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.

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:
That which is removed says:
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.

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.

ADOMAH Periodic Table Glass Cube
This amazing object is available for sale from Grand Illusions:
A Note by Philip Stewart firstname.lastname@example.org
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, email@example.com, creator of the design, has written to me as follows:
Adomah is a variant of Adamah, Hebrew for 'dust of the earth', from which Adam was made (Genesis 2:7).

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."
Jodogne's Janet New Colour Periodic Table
"This Periodic Table(click here for larger version) incorporates the Real Aufbau of Professor Pyykkö based on relativistic Quantum Mechanics, with Z continuity horizontally and vertically, by means of taking into account the ground level - energy increase upward - of the last incoming electron (the lower side of the element case is the level guide mark).

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.

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:-

Srivaths–Labarca Periodic Table
In the new Srivaths–Labarca arrangement, the three main criteria proposed for the position of hydrogen and helium are simultaneously taken into account. Consequently, hydrogen is in between alkali metals and halogens, whereas helium is midway between the noble gases family and the alkaline earth elements.
Eric Scerri has critiqued this paper and periodic table here.

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.
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.
