in a broad sense oxidation is the increase in positive valence of any element in a substance. On the basis of the electron theory, oxidation is a process in which an element losses electrons. In a narrow sense, oxidation means the chemical addition of oxygen to a substance.

(1) The complete, net removal of one or more electrons from a molecular entity (also called 'de-electronation'). (2) an increase in the oxidation number of any atom within any substrate (see HENDRICKSON, CRAM and HAMMOND (1970)). (3) Gain of oxygen and/or loss of hydrogen of an organic substrate. All oxidations meet criteria (1) and (2), and many m

This is a reaction with oxygen, as in combustion. An oxidized molecule is generally one that has lost electrons. Reduction also takes palce during oxidation - if one substance is oxidised then anothr must be reduced.

oxidize; oxidizing; oxidized. Compare with reduction. Oxidation is the loss of one or more electrons by an atom, molecule, or ion. Oxidation is accompanied by an increase in oxidation number on the atoms, molecules, or ions that lose electrons.

The term oxidation originally meant a reaction in which oxygen combines chemically with another substance. More generally, oxidation is a part of a chemical reaction in which a reactant loses electrons (increase oxidation number). Simultaneous reduction of a different reactant must occur (redox reaction).
