The oxidation number of zinc in Zn is typically +2.
What compounds contain zinc?
Zinc chloride, ZnCl2 Zinc sulphate, ZnSO4 Zinc nitrate, Zn(NO3)2
Why are compounds of zinc white but compounds of copper have color?
Compounds of zinc are white because zinc atoms do not absorb visible light in the same way that copper atoms do. Copper compounds have color because copper atoms absorb certain wavelengths of visible light, leading to the perception of color in the compound. This difference in electronic structure is responsible for the variation in color between compounds of zinc and copper.
Does zinc usually combine with copper?
Alloys of zinc and copper are well known. There are no chemical compounds of zinc and copper.
