Complete step by step … WebCertain elements have more than one valency. They exhibit variable valency. For example, copper, tin, iron and mercury exhibit variable valency. Copper combines with oxygen to form cuprous oxide (Cu 2 O) and cupric oxide (CuO). Valency of oxygen being two, combining capacity of copper in the first case is one and that in the second case is two.

Because of the ambiguity of the term valence, other notations are currently preferred. Beside the system of oxidation states (also called oxidation numbers) as used in Stock nomenclature for coordination compounds, and the lambda notation, as used in the IUPAC nomenclature of inorganic chemistry, oxidation state is a more clear indication of the electronic state of atoms in a molecule.
