Oxidation number is the apparent ionic charge of an element in a compound if we assume that the bonds in the compound are completely ionic, which of … Oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.. Each atom that participates in an oxidation-reduction reaction is assigned an oxidation number that reflects its ability to acquire, donate, or share electrons. A potent oxidant is needed to oxidize noble gases and form compounds in positive oxidation states.

Hydrogen forms three oxidation states, -1 , 0 , +1. Group 14 elements all have a +4 oxidation number (although some of them are also +2). Electronic Configuration . 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. What is to bolster as Battery is to torch? 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.
