The INTERNET Database of Periodic Tables

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

New Periodic Table of the Elements Based on the Structure of the Atom

Tomkeieff SI, 1954, A New Periodic Table of the Elements Based on the Structure of the Atom, Chapman & Hall, London.

Thanks to René Vernon for the tip, who writes:

It is a helix wrapped on the surface of a cone. The shadow on the left is from the edge of my hand holding down the table; the shadow on the right is from the edge of a different book, again used to hold down the table into some semblance of flatness.

Mazurs said: "This is not a very successful table".

First, there is the cumbersome nature of a table on a cone, Secondly, see how the eight main group numbers at the top are sort of mushed into the 18 A and B series group numbers. This does not work well.

The colour scheme shows the dominant acid-base properties of the elements:

Dark blue — strong bases
Light blue — weak bases
Light red — weak acids
Dark red — strong acids
White — Inert gases

Since nonmetals never form basic oxides it is interesting to note that the (23) nonmetals fall on the right side of the table:

H He
B C N O F Ne
Si P S Cl Ar
Ge As Se Br Kr
Sb Te I Xe
Rn

[Water is amphoteric; hydrogen peroxide is weakly acid.]

While the underlined elements are sometimes called metalloids, it is has been known for over 100 years that metalloids predominately behave chemically like nonmetals.

Astatine would’ve been a nonmetal but for relativistic effects. Immediately following its production in 1940, early investigators considered it a metal.
