Gold is a chemical element with the symbol Au from Latin: aurum and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental native form, as nuggets or grains, in rocks, in veins, and in alluvial deposits
