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 Mercury was discovered by unknown in year 1500 BC in unknown place. Mercury derived its name derived its name from from the New Latin name mercurius, named after the Roman god (Hg from former name hydrargyrum, from Greek hydr-, 'water', and argyros, 'silver')
