The combination of any substance with oxygen is referred to as oxidation. Many chemicals combine with oxygen to facilitate this process. Oxidation is the deficiency of electrons for the period of a reaction by a molecule, atom, or ion.
Oxidation ensues when the oxidation state of a molecule, atom, or ion is enhanced. Oxidation means any reaction where oxygen is combined with another molecule, which is called oxidized. One glucose molecule merge with six oxygen molecules to create six carbon dioxide molecules, six water molecules, and adenosine triphosphate during the process.
It is said to be the reaction between oxygen to everything, including living tissue. The oxidation state, which may be positive or negative, or zero, is the hypothetical charge that an atom would possess if all bonds to atoms of various elements were 100 percent ionic with no covalent component is never entirely true for real bonds.
