Symbol, Ga; at. wt., 69.9. Gallium is chiefly trivalent, resembling aluminium and indium. It was predicted with most of its properties, under the name eka-aluminium, by Mendelyeev on the basis of the periodic law.

Medical Definition of Gallium

1. A rare metallic element, found in certain zinc ores. It is white, hard, and malleable, resembling aluminium, and remarcable for its low melting point (86 F, 30C). The element was predicted with most of its properties, under the name ekaluminium, by the Russian chemist Mendelejeff, on the basis of the Periodic law. This prediction was verified in its discovery by the French chemist Lecoq de Boisbaudran by its characteristic spectrum (two violet lines), in an examination of a zinc blende from the Pyrenees.
