Gallium: historical information

Gallium was discovered by Paul-Emile Lecoq de Boisbaudran at 1875 in France. Origin of name: from the Latin word "Gallia" meaning "France" and perhaps also from the Latin word "gallus", (the cock, a translation of Lecoq, the discoveror of gallium).

Gallium was an element whose existence was predicted by Mendeleev in 1871. He predicted that the then unknown element gallium should resemble aluminium in its properties. He suggested therefore the name ekaaluminium (symbol Ea). His predictions for the properties of gallium are remarkably close to the reality. Gallium was discovered spectroscopically by Paul-Emile Lecoq de Boisbaudran in 1875, who in the same year obtained the free metal by electrolysis of a solution of the hydroxide Ga(OH)3 in KOH.
