CRC periodic table, 1924

One more periodic table: from the 1924 CRC Handbook of Chemistry and Physics, which one of my ancestors picked up somewhere.


This periodic table has 79 elements, as opposed to the 117 on the current periodic table, 90 of which are naturally-occurring.

The familiar modern layout of the periodic table (as on my previous post) was developed by Glenn Seaborg in the 1940s as the trans-uranium elements were being created.

Grace and Peace
