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).

Russian Periodic Table(s)

Eric Scerri writes:

"The periodic tables [below], and data, are from some Russian books given to me by the late Ray Hefferlin, when I visited him a few years ago in Tennessee. Sorry, I can't give any source details as the inserts got separated from the book."

The captions say: "Fig. XVII. Block-type periodic table" and "U.L.Kulakov, Classification of the chemical elements on the new background".

Looking at the graphics style, we are guessing they date from the mid-1970s (MRL)
