An oxidation is when an atom loses an electron to another atom. For example, when hydrogen combines with oxygen to make water, the hydrogen loses an electron and is oxidized.
An oxidizing agent is an atom which can easily gain electrons from other atoms. Oxygen, fluorine and ozone are examples. The shell model of the atom explains why oxidations occur. When one atom is oxidized, some other atom must be reduced. Oxidation is commonly called "burning", and happens either quickly, as in a fire, or slowly, as when a cut apple turns brown. Remember OILRIG (Oxidation Is Loss, Reduction Is Gain) |
