History

History
The element Berkelium was discovered by Lawrence Berkeley National Laboratory in year 1949 in United States. Berkelium derived its name from from Berkeley, California, where the element was first synthesized, by analogy with terbium
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
