History

History
The element Niobium was discovered by Charles Hatchett in year 1801 in United Kingdom. Niobium derived its name from from Niobe, daughter of king Tantalus from Greek mythology
The element Samarium was discovered by Lecoq de Boisbaudran in year 1879 in France. Samarium derived its name derived its name from from Samarskite, the name of the mineral from which it was first isolated
