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 Aluminium was discovered by in year 1825 in Denmark. Aluminium derived its name derived its name from from alumina, a compound (originally aluminum) |
