leads to the conclusion that gold actually occupies a unique position among the elements. There are several consequences of this effect in gold chemistry: 1. The color of gold. Gold has an absorption beginning at 2.4eV, attributed to a transition from the filled 5d band to the Fermi level (essentially the 6s band). It
