It is well known that the oxidation of an organic compound is a function of the number of electrons (or protons) missing in the molecule in question. So, oxidation is a physical process, which is affected by heat, light, and other factors. With the oxidation number, you can tell a little bit about the stability of the compound or chemical or compound.
For the oxidation number, we’re looking at the number of electrons or protons missing in the oxygen molecule in question. In this case, oxidation of oxygen is a function of the number of electrons missing in the oxygen molecule. In this case, oxidation of water is a function of the number of protons missing in it.
The oxidation number tells you about the stability of a molecule.
