Gold is a soft metal that is largely unreactive. Gold jewellery can lie underground for thousands of years and emerge shiny after that lengthy exposure to air‚ water‚ and other chemicals in the environment. Gold does dissolve in some solvents as indicated below and does react with halogens. The most common oxidation states of gold are Au(I) and Au(III) but there are a few examples of Au(V) (various anions [AuF6]- and [Au2F10]). The Au(III) ion has the d8configuration which gives rise to many square
