It has been long understood that some elements tend to be found as sulfides in nature, whilst others as oxides. The importance has been recognized by both chemists and geologists, but chemists were unable to interpret the reason for such difference in occurrence. The abundance of the elements in the space is determined by the characteristics of the nuclides of the elements; i. e. by the rate at which the particular nuclide is synthesized from lighter nuclides. On the other hand, the chemical form of the elements in nature is largely dependent on the electronic structure of the atoms. Recent studies of the stability of various coordination compounds in aqueous solution give useful information for interpreting the affinities of elements towards oxide and sulfide.
