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)

Hyde's Periodic Relationships of The Elements (updated)

I received an email from Jeremy Sachs saying:

"Gelest don't seem to offer [this periodic table formulation] anymore, and because their version heavily modifies Hyde's original table, I've reproduced the 1975 version of his table with the permission of his surviving relatives."
