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 Lead was discovered by Middle East in year 4000 BC in unknown place. Lead derived its name derived its name from from English word (plumbum in Latin)
