Gallium. The existence of gallium was predicted in 1871 by Mendeleev, who called it ekaaluminium. In 1875 Lecoq de Boisbaudran, whose curiosity had been aroused by the presence of unknown lines in the spectrum of a zinc mineral originating from the Pyrenees, succeeded in isolating the metal, which he named gallium after his native France (Gallia).

Germanium is a chemical element with the symbol Ge and atomic number 32. It is a lustrous, hardbrittle, grayishwhite metalloid in the carbon group, chemically similar to its group neighbours silicon and tin.Pure germanium is a semiconductor with an appearance similar to elemental silicon. Like silicon, germanium naturally reacts and forms complexes with oxygen in nature.
