7 Jan 1940 Jahr - Current Periodic Table

Beschreibung:

The last major change to the periodic table was made by Glenn Seaborg in 1951. In 1941, he discovered plutonium and then continued to discover all the transuranic elements from 94 to 102. He reconfigured the periodic table by placing the actinoid series below the lanthanoid series at the bottom of the table.
