Eric Scerri's Triad Periodic Table

Eric Scerri says, "I have recently developed a new periodic table with some very nice features. I am now shifting my allegiance from the left-step table to this one."

Read the paper on the philosophy of science web site.

Homeopathic

A Homeopathic Periodic Table by Jan Scholten.

From his book Geheime Lanthanide (Secret Lanthanides) 2006. The basic idea is that successive elements in each series ( = row) are like the stages in a heroic story like the labours of Hercules or the voyages of Odysseus, each one appropriate to meet a different challenge.

ADOMAH Periodic Table by Valery Tsimmerman

The ADOMAH periodic table is based on the Janet or left-step periodic table. It consists of four blocks (s, p, d & f) corresponding to quantum numbers l = 0,1,2,3. Blocks are separated, shifted and reconnected with each other via diagonal lines. This arrangement creates "layers" or "strata" that retain continuity in respect to atomic number Z, in addition to usual columns and rows. Therefore, numbers shown on the right hand side of the table may represent either quantum numbers n (electronic shells) if horizontal rows are followed, or n + l if "layers" or "strata" are followed.

This feature assists in creation of electronic configurations of the elements. Elements H and He are placed in two positions that reflect their dual nature and give proper consideration to atomic structure and chemical properties of those two elements. This feature also preserves triads He, Ne, Ar and H, F, Cl. Also, the elements are placed in rectangular "boxes", so any two of such "boxes" make up a square thus symbolising electron pairs. This also cuts table length in half. Unlike the Janet table, this table is assembled from bottom up in direction of increase of quantum number n, as well as atomic weight and energy. The ADOMAH table has symmetry and, assuming total number of elements 120, can be divided in four parts of 30 elements with center point located among precious metals.

Reaction Chemists' Periodic Table

OK, so which Is The Best formulation of The Periodic Table?

Personally as a reaction chemist, my preferred periodic table is the 'long' form shown below, with hydrogen above and between boron and carbon, although clearly other scientists have other ideas.

All periodic tables show the increase in mass and atomic number, Z, but only the long form unambiguously shows the general top-right-to-bottom-left trends in electronegativity, atomic radius, metallic properties and first ionisation energy.

Electronegativity is absolutely crucial to the understanding of structure, bonding, material type (van Arkel-Ketelaar triangle and Laing tetrahedron) and chemical reactivity, and it underpins much of the chemogenesis analysis.

2006 Schemata of the Elements

"The conventional periodic table reflects what is called the aufbau design, which represents a progression of numbers; in this case, that of the atomic number of the elements. The table, however, contradicts the aufbau concept in reality, because there are large gaps within among the primary (representative) elements, as well as in relation to the tertiary elements (transition and inner transition elements). The latter case, the Lanthanoids and the Actinoids, lie completely outside of the main body of the periodic table, thereby effectively breaking down the aufbau design... more..." from here by Charles William Johnson:

Various Periodic Tables

As discussed on this page of the Chemogenesis webbook, the periodic table is ambiguous as to what it is showing.

Does the PT show the element as the abstract 'basic substance', or gas phase atoms or the material substance?

Demers' Système du Québécium

Updated from this 2002 entry comes: Quebec System, Numbers and geometry in the classification of the elements by Pierre Demers.

Demers writes:

"First, I present the Periodic Table of Elements, and I proceed to improve it. By an arithmetic and geometrical analysis, I make appear important symmetries of order four which exist in the arrangement of the atoms between them. I confirm these results with an original discussion of irregular atoms. I will try, in a work that will follow, to interpret the symmetries of the classification by the symmetries of the atom which are associated with the precession cones of the kinetic moments and orbitals."
