The INTERNET
Database of Periodic Tables

There are hundreds of periodic tables in web space, but there is only one comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Dr Mark R Leach.

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:
