History

History
The element Promethium was discovered by Chien Shiung Wu in year 1945 in United States. Promethium derived its name from from Prometheus of Greek mythology who stole fire from the Gods and gave it to humans
The element Plutonium was discovered by Glenn T. Seaborg in year 1940 in United States. Plutonium derived its name derived its name from from Pluto, a dwarf planet in the Solar System (then considered the ninth planet)
