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 Silicon was discovered by Jöns Jacob Berzelius in year 1824 in Sweden. Silicon derived its name derived its name from from the Latin silex, 'flint' (originally silicium)
