Gold is a chemica element with symbol Au (from Latin:Aurum) and atomic number *9.In it's purest form, it ia a bright, slightly reddish-yellow, dense, soft, malleable and ductile metal.Chemically, gold is a transition metal and a group *1 element.It is one of the least reactive chemical elements and is solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains, in rocks, in veins and in alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum) and also naturally alloyed with copper and palladium. Less commonly, it occurs in minerals as gold compounds, often with tellurium ( gold tellurides).
Gold's atomic number of *9 makes it one of the higher atomic number elements that occur naturally in the universe.
