Definition of Gallium

1. Noun. A rare silvery (usually trivalent) metallic element; brittle at low temperatures but liquid above room temperature; occurs in trace amounts in bauxite and zinc ores.

Definition of Gallium

1. n. A rare metallic element, found in certain zinc ores. It is white, hard, and malleable, resembling aluminium, and remarkable for its low melting point (86° F., 30° C). Symbol Ga. Atomic weight 69.9.

2. n. 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, 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. This prediction was verified in its discovery (in 1875) by its characteristic spectrum (two violet lines).

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.
