Oxidation is the process when oxygen combines with an element, changing the appearance of the element. When iron reacts with oxygen and changes to rust, this is an example of oxidation.
The increase in oxidation state of an atom, through a chemical reaction, is known as an oxidation; a decrease in oxidation state is known as a reduction. Such reactions involve the formal transfer of electrons: a net gain in electrons being a reduction, and a net loss of electrons being an oxidation. For pure elements, the oxidation state is zero.
