History

History
The element Gallium was discovered by Lecoq de Boisbaudran in year 1875 in France. Gallium derived its name from from Gallia, the Latin name for France
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
