Mineral Species sorted by the element Ga Gallium (original) (raw)

Gallium (Ga) Element Properties

Atomic Mass 69.723
Atomic Number 31
Name Origins Latin, Gallia = "France."
Year Discovered 1875
Discovery Credits Discovered by Paul-Emile Lacoq de Boisbaudran at Paris, France.
Remarks Soft, silvery-white metal, stable in air and with water. Soluble in acids and alkalis. Longest liquid range of all elements. Semiconductor properties with nitrogen, phosphorus, arsenic, and antimony. Used in light-emitting diodes; microwave equipment.Diagnostic tests: there are no simple chemical tests for gallium. Atomic Absorption Spectroscopy is used for quantitative analysis and Energy Dispersive Analysis of X-rays (EDAX) is used for qualitative analysis.
