Gold is currently considered the heaviest monoisotopic element. Bismuth formerly held that distinction until alpha-decay of the 209 Bi isotope was observed. All isotopes of gold are either radioactive or, in the case of 197 Au, observationally stable , meaning that 197 Au is predicted to be radioactive but no actual decay has been observed.

Gold compounds are compounds by the element gold (Au). Although gold is the most noble of the noble metals , [ 1 ] [ 2 ] it still forms many diverse compounds. The oxidation state of gold in its compounds ranges from −1 to +5, but Au(I) and Au(III) dominate its chemistry.
