The chemical reactions in which both oxidation and redox reactions take place simultaneously are called as redox reactions.
A chemical reaction is said to be oxidation reaction if it involves either loss of electrons or increase in oxidation state.
A chemical reaction is said to be reduction reaction if it involves either gain of electrons or decrease in oxidation state.
Oxidation number denotes the oxidation state of an element in a compound ascertained according to a set of rules formulated on the basis that electron in a covalent bond belongs entirely to more electronegative element
The oxidation number of the element in the free or elementary state is always zero.
The common oxidation state of oxygen in its oxides is '-2'.
The common oxidation state of iodine is '-1'.
The common oxidation state of alkali metals is '+1'.
