History

History
The element Americium was discovered by Glenn T. Seaborg in year 1944 in United States. Americium derived its name from from The Americas, as the element was first synthesized on the continent, by analogy with europium
The element Berkelium was discovered by Lawrence Berkeley National Laboratory in year 1949 in United States. Berkelium derived its name derived its name from from Berkeley, California, where the element was first synthesized, by analogy with terbium
