The Periodic Stack of Elements

Observation
The Janet Periodic Table (1921) is an interesting 2D arrangement of the natural elements. Further information on the Janet table may be found at;
http://www.ipgp.jussieu.fr/~tarantola/

The Janet table can be arranged as a series of four square matrices. Each matrix is a differnt size. Each matrix arranges the orbitals (s,p,d,f) into a series of concentric rings. The “s” ring is the core and the other orbitals form concentric rings around the core. Elements which are located on a major diagonal have the quantum number for orbital magnetic moment (mL) equal to zero.

The matrices may be stacked vertically with the core elements aligned vertically. This is a 3D arrangement of the natural elements which I call the Periodic Stack of Elements. Vertical sections through the stack give interesting groupings of elements.

From observations it is possible to deduce a 2x3 martix of quantum numbers.
The top row is; n , L , s
The bottom row is; mn , mL , ms
The quantum number mn may represent the magnetic moment of precession.

At this point the URL: http://ca.geocities.com/chemguy777/index.htm
receives only the following response:

“Sorry, the GeoCities web site you were trying to reach is no longer available.

GeoCities has closed,…!”
Therefore, one is unable to see this item at the indicated location.

This table can be seen and evaluated now at : http://www.ipgp.fr/~tarantola/Files/Professional/Mendeleev/

Instead of running from left to right—which is the original Mendeleev’s way— it goes the opposite way, beginning with the Hydrogen-1 and He-2 at the top, right corner of the table. Thus one, has to read it backwards, which is awkward in the usual way of reading from left to right. It might be more readable in a vertical mirror, or else become useful if it was written with the H1 and He2 in the usual place without giving up the idea of following the filling up of the electron orbital energy level filling idea. The other problem it assigns a huge space to the lanthanides —that occupy almost two thirds of the space in the periodic table, while cramming the rest of the elements into one third of the table. Thus, it is not a very handy reference table for the chemist, and it is very unlikely that it would be adopted anywhere anytime soon. Granted that the filling up of the electron orbitals does provide some useful insight to the physicist or physical chemist, provided that the mirror representation of the table would be used, beginning the Table at the left of the page instead of beginning it at the right, as we are used to writing from left to write. It might have a definite advantage only for left-handed persons, or groups who write and print from right -to-left. Reading the elements starting at 138 and Ac-139, and ending with He2 at the topmost right hand corner, is unnerving at best.

Originality: 1, Importance: 2, Overall quality: 2

It would be interesting to see the 3D-version suggested by the author, hopefully represented with the usual convention of writing, form left-to-right, not backwards.

The promised further details are no longer available at the Geo City, which is now closed, according to the web search engines.
