Gold (Au) Element Properties

Atomic Mass 196.96654
Atomic Number 79
Name Origins Anglo-Saxon, gold
Year Discovered Prehistoric
Discovery Credits Known to pre-historic humans
Remarks Soft metal with characteristic yellow color. Highest malleability and ductility of any element. Unaffected by air, water, acids (except HNO3-HCl), and alkalis. Used as bullion, in jewelry, electronics, and glass.Diagnostic tests: Commonly occurs as the native element. Gold is easily reduced from it's minerals on charcoal by heating in the reducing flame. The resultant metallic bead is gold in color and malleable.
