By definition, a redox reaction is one that entails changes in oxidation number (or oxidation state) for one or more of the elements involved. The oxidation number of an element in a compound is essentially an assessment of how the electronic environment of its atoms is different in comparison to atoms of the pure element. 5.8 Redox chemistry. An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron. Reduction is a part of a redox reaction. It involves the half reaction in which a chemical species decreases its oxidation number, usually by gaining electrons. This process is considered as the opposite of the oxidation process.
