gallium


From The Collaborative International Dictionary of English v.0.48:

Gallium \Gal"li*um\, n. [NL.; perh. fr. L. Gallia France.]
   (Chem.)
   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[deg] F., 30[deg]
   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 the
   Russian chemist Mendelyeev on the basis of the periodic law.
   This prediction was verified in its discovery (in 1875) by
   the French chemist Lecoq de Boisbaudran by its characteristic
   spectrum (two violet lines), in an examination of a zinc
   blende from the Pyrenees.
