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., 30?C). Symbol
Ga. Atomic weight 69.9.
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.
