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 Actinium was discovered by Friedrich Oskar Giesel in year 1899 in France. Actinium derived its name derived its name from from the Greek aktis, 'ray'
