A rare metallic element, found combined in certain zinc ores. It is white, hard, and malleable, resembling aluminium, and remarkable for its low melting point (86° F., 30° C.). Symbol, <i>Ga</i>; at. wt., 69.9. Gallium is chiefly trivalent, resembling aluminium and indium. It was predicted with most of its properties, under the name <i>eka-aluminium</i>, by Mendelyeev on the basis of the periodic law. This prediction was verified in its discovery (in 1875) by its characteristic spectrum (two violet lines).
