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 Arsenic was discovered by Bronze Age in year 1250 in unknown place. Arsenic derived its name derived its name from English word (Latin arsenicum)
