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 Curium was discovered by Glenn T. Seaborg in year 1944 in United States. Curium derived its name derived its name from from Pierre Curie, a physicist, and Marie Curie, a physicist and chemist, named after great scientists by analogy with gadolinium
