Electronic configuration Gold is the chemical element with atomic number 79 and its symbol is Au (from the Latin aurum). It is a soft, heavy, ductile, malleable yellow transition metal, due to the absorption of blue wavelengths by incident light. Resistant to most chemical compounds, it reacts in practice only with aqua regia and the cyanide ion. With mercury it forms an amalgam, but not a chemical compound. It is found in the native state in the form of nuggets, grains and specks in rocks and alluvial deposits. It has been used since ancient times to mint coins and, before the advent of fiat money (Latin for "made", ie created from nothing, as it is today) has been used as a countervalue for the currency issues of the States, as was the case with the so-called gold standard. It is also used in jewelry, dentistry and in the electronics industry. Its ISO code as a currency is XAU (equivalent value per ounce of metal). #Au #Au79 #Gold
