The outer electron configuration of the gold atom is 5d 10 6s 1. In compounds the valences of gold are 1 and 3. (Complex compounds are known in which gold is bivalent.) Gold does not react with nonmetals (except for halogens). It forms halides with halogens; for example, 2Au + 3Cl 2 = 2AuCl 3.
An earlier form of compound developed in South Africa in response to copper mining in Namaqualand in the 1850s. However, the systems of control associated with labour compounds became more organized in the context of diamond mining at what became Kimberley from the early 1870s.. By 1872 more than 50 000 people had converged on the Diamond Fields.The newspaperman R.W. Murray
