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 Cadmium was discovered by Karl Samuel Leberecht Hermann in year 1817 in Germany. Cadmium derived its name derived its name from from the New Latin cadmia, from King Kadmos
