Soluble compounds ( gold salts) such as gold chloride are toxic to the liver and kidneys. Common cyanide salts of gold such as potassium gold cyanide, used in gold electroplating, are toxic by virtue of both their cyanide and gold content. There are rare cases of lethal gold poisoning from potassium gold cyanide. [215] [216] Gold toxicity can be ameliorated with chelation therapy with an agent such as dimercaprol. Craig, B.

ISBN 9781444394870Gold readily dissolves in mercury at room temperature to form an amalgam, and forms alloys with many other metals at higher temperatures. These alloys can be produced to modify the hardness and other metallurgical properties, to control melting point or to create exotic colors. [24]

The symbol Au is from the Latin: aurum, the Latin word for "gold". [110] The Proto-Indo-European ancestor of aurum was *h₂é-h₂us-o-, meaning "glow". This word is derived from the same root (Proto-Indo-European *h₂u̯es- "to dawn") as *h₂éu̯sōs, the ancestor of the Latin word Aurora, "dawn". [111] This etymological relationship is presumably behind the frequent claim in scientific publications that aurum meant "shining dawn".
