01 About Plutonium

Does not exist in nature (except in trace amounts). Created in nuclear reactors from U-238. Warm to the touch from its own radioactive decay. The most complex electronic structure of any element.

03 Discovery

Plutonium was discovered in 1940 by Seaborg et al..

As a actinide, Pu appears in the f-block of the periodic table and has complex electron configurations that make it chemically interesting. โ†’ See nuclear elements on NexoHub
