This is not strictly true. Gold by itself will not oxidize, but when in
contact with a metal with a lower electro-negativity, it will act as a
sacrificial anode. For example a gold coin in salt water will not
corrode, but if you put an iron nail in the gold coin in salt water, the
gold will corrode and prevent the corrosion of the iron.
