Oxidation number:Oxidation State is the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
An oxidation number is a number that is assigned to an atom in a substance. The oxidation number could be positive, negative, or zero, and it indicates if electrons are lost or gained. In other words, the oxidation number is a number that helps us keep track of electrons in an atom. The oxidation number of calcium is +2 and the oxidation number of oxygen is -2.
