GALLIUM
Gal"li*um, n. Etym: [NL., fr. L. Gallia France.] (Chem.)
Definition: 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
Note: 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.
