History

History
The element Samarium was discovered by Lecoq de Boisbaudran in year 1879 in France. Samarium derived its name from from Samarskite, the name of the mineral from which it was first isolated
The element Iron was discovered by unknown in year 2000 BC in unknown place. Iron derived its name derived its name from from English word (ferrum in Latin)
