Description: Gold is a soft metal with a characteristic shiny yellow colour. It has the highest malleability and ducility of any element, and can be beaten into a film only microns thick. Gold is unaffected by air, water, acids (exept aqua regia, HNO3-HCl) and alkalis. It is used as bullion, in jewellery, electronics and glass, to colour it and as a heat reflector.
