Gold

Gold is a chemical element in the periodic table that has the symbol Au and atomic number 79.

A soft, shiny, yellow, dense, malleable, ductile transition metal, gold does not react with most chemicals but is attacked by chlorine, fluorine and aqua regia.

The metal occurs as nuggets or grains in rocks and in alluvial deposits and is one of the coinage metals.
