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. The database holds information on periodic tables, the discovery of the elements, the elucidation of atomic weights and the discovery of atomic structure (and much, much more).

Ageev's Crystalline Structures of The Elements
Ageev NV 1947, The nature of the chemical bond in metal alloys (Izdvo Akad. Nauk SSSR, Moscow/Leningrad, p. 10
René Vernon writes:
"In this curious 18-column table, showing the crystalline structures of the elements, Ageev locates the predominately non-metallic groups on the left and the remaining groups on the right.
"It's odd that he located boron and aluminium on the far left over gallium, rather than over scandium. I suppose he did this so that gallium, indium, and thallium would not be mistaken for d-block metals.
"Reading from left to right then, Ageev's table could be said to be made up of five blocs:"
[1] the nonmetallic bloc
[2] the alkaline bloc
[3] the inner transition bloc
[4] the transition metal block
[5] a post-transition metallic bloc
