History

History
The element Fermium was discovered by Lawrence Berkeley National Laboratory in year 1952 in United States. Fermium derived its name from from Enrico Fermi, physicist
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
