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 Cobalt was discovered by Georg Brandt in year 1735 in Sweden. Cobalt derived its name derived its name from from the German word Kobold, meaning 'goblin'
