Oxidation Number Definition:
A number given to an atom in a compound which describes how oxidised or reduced it is is called oxidation number.
Cambridge International AS and A Level Chemistry by Ryan Lawrie, Roger Norris
Oxidation Number Notes:
The oxidation number of an atom is the charge of an atom if the compound was composed of ions. 1. The oxidation number of an atom is zero in a neutral substance that contains atoms of only one element. for example, the atoms in O2, O3, P4, S8, and aluminum metal all have an oxidation number of 0.The oxidation number of sodium in the Na+ ion is +1,, and the oxidation number of chlorine in the Cl- ion is -1.It is useful in following chemical reactions by examining at changes in the oxidation numbers of the atoms in each compound during the reaction. Oxidation numbers also perform an important role in the systematic nomenclature of chemical compounds.
