History

History
The element Plutonium was discovered by Glenn T. Seaborg in year 1940 in United States. Plutonium derived its name from from Pluto, a dwarf planet in the Solar System (then considered the ninth planet)
The element Neptunium was discovered by Edwin McMillan in year 1940 in United States. Neptunium derived its name derived its name from from Neptune, the eighth planet in the Solar System
