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) |
