Oxidation Number of Group 16. 2.44. The oxidation number of a Group VIIA element in a compound is -1, except when that element is combined with one having a higher electronegativity. Electronic Configuration . It wants to have eight, so it will gain three electrons. But then group 14 has a number of 4+ or minus (-). Group 15 elements consist of nitrogen, phosphorus, arsenic, antimony and bismuth. The higher oxidation state is obtained when all the ns and np electrons from ns2p x configuration of p-block elements ( x = 1,2,3 and 4 for the elements of groups IIIA, IVA, VA, and VIA respectively) are lost. Because the halogens are highly reactive, none is found in nature as the free element. The alkaline earth metals (group II) are always assigned an oxidation number of +2.

Oxidation State and valency are one of the most fundamental properties of elements and can be studied with the help of electron configurations. O. The alkali metals (group I) always have an oxidation number of +1. Electronegativity. A potent oxidant is needed to oxidize noble gases and form compounds in positive oxidation states. The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation (loss of electrons) of an atom in a chemical compound.Conceptually, the oxidation state, which may be positive, negative or zero, is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic, with no covalent component.
