Direct link to Richard's post The symbol for potassium,, Posted 4 years ago. Copper monosulfide is a chemical compound of copper and sulfur.It was initially thought to occur in nature as the dark indigo blue mineral covellite.However, it was later shown to be rather a cuprous compound, formula Cu + 3 S(S 2). Large quantities of the compound are obtained by heating cupric sulfide (CuS) in a stream of hydrogen. Cuprous oxide readily converts to copper metal upon heating. Give an example. The formulation should not be interpreted as containing radical anion, but rather that there is a delocalized valence "hole". ChemTeam: Nomenclature-Binary Compounds:Stock [6] Investigations of covellite (CuS) indicate that there are other metastable Cu-S phases still to be fully characterised.[1]. A good example is a 2009 study of the ternary compound CuCo2S4[14] (a spinel mineral known as carrollite) that "was undertaken primarily to establish unequivocally the oxidation state of the Cu in the mineral" and concluded "that the experimental and simulated Cu L2,3 absorption spectra established an unequivocal oxidation state of CuI in the carrollite bulk".

There is also an amorphous high pressure form[9] which on the basis of the Raman spectrum has been described as having a distorted covellite structure. The combination of oppositely charged ions results in the formation of compounds that act as electrolytes because they easily dissociate into their constituent ions. Copper monosulfide can be prepared by passing hydrogen sulfide gas into a solution of copper(II) salt. What is the formula for the ionic compound formed by the ions Al3+ and S2-?
