Lado's Periodic Table Series Analysis
By Solomon F Lado, a mathematical analysis.
Abstract (full paper):
"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 20c^{2} – 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 cconstruction index and the cconstructionindex formulae are unique to this report. The maximum number of potential orbitals per subshell of an atom = 3^{n1} where n is the index of the s, p, d, and f subshells":

ADOMAH Periodic Table Glass Cube
Valery Tsimmerman, of the ADOMAH Periodic Table and the ADOMAH Tetrahedron, has now used these ideas to produce a beautiful glass cube:
This amazing object is available for sale from Grand Illusions:
A Note by Philip Stewart stewart.phi@gmail.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 2D 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 m_{l}).

Valery Tsimmerman, orahct@gmail.com, 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, m_{l} 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 m_{l} 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."
Adomah is a variant of Adamah, Hebrew for 'dust of the earth', from which Adam was made (Genesis 2:7).

Zambon's Periodic Table Based on Triads
Alfio Zambon – Universidad Nacional de la Patagonia
1. Introduction
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.

Rogue Elements: What's Wrong with the Periodic Table
An article in New Scientist by Celeste Biever (news editor at Nature), Image by Martin Reznik
Weights gone awry, elements changing position, the ructions of relativity – chemistry's iconic chart is far from stable, and no one knows where it will end
IF IMITATION is the sincerest form of flattery, the periodic table has many true admirers. Typefaces, types of meat and even the Muppets have been ordered in its image. For chemists, knowing an element's position in the periodic table, and the company it keeps, is still the most reliable indicator of its properties – and a precious guide in the search for new substances. "It rivals Darwin's Origin of Species in terms of the impact of bringing order out of chaos," says Peter Edwards of the University of Oxford.
The origins of the periodic table lie in the 19th century, when chemists noticed that patterns began to emerge among the known chemical elements when they... click here to continue:

Chandra's Polar Plot Periodic Table
MONOGRAPH ON ATOMS, BY Dr. N. Naveen Chandra, 543 Bellamy Road North Scarborough, On, M1H1G5, 416 439 6630, chandraalex@hotmail.com >© N.Naveen Chandra, 2014.
Abstract
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
"I would like to submit you an hexagonal periodic table. It's structured in different rings. The elements are ordered on their metallic characters so in the inner rings there are noble gases and nonmetals while in the outer rings there are alkali and alkaline earth metals. I based the order on the typical metallic characteristics: low ionization energy, electron affinity, etc... "

Janet Rajeuni
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 nonmetals at its head (and that half its members are nonmetals), 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."

A large yellow line indicates period. A gradual color for H induces a manifold chemical behavior."

The current and present modern notation scheme for the groups in the Periodic Table exist from 1985, proposed from the IUPAC Commission on the Nomenclature of Inorganic Chemistry, as recommendation. This proposal was also verified in 2005.
Because the IUPAC Commission encourages further discussions, improvements and proposals on this subject I made this new article which article investigates the possibilities for the new notation scheme in the Periodic Table. Links:

Arrangement of Elements 7th Order & Element Sequences
An exploration of some mathematics underlying the periodic table, read the PDF here, by Olivier Joseph.
Oliver says:
"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
DOI: 10.4236/jmp.2014.53020
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 sblock, should be placed beside hydrogen in the sblock instead of the pblock. Lutetium and lawrencium belonging to the dblock of the transition metals should not be in the fblock of the lanthanides or the actinoids. With these slight modifications, the IUPAC table becomes quantum mechanics consistent.
