Electrons can be moved from a lower energy state in one atom to a higher energy state in another atom; this serves to _______ energy. Electrons can also move from higher energy states in one atom to lower energy states in another, thus _______ energy. The movement of electrons from one atom to another changes the _______ number of both atoms. Any chemical reaction that changes the oxidation number of atoms is called a _______ reaction.

The term redox is a combination of the terms reduction and oxidation. _______ is the gain of electrons, which decreases the _______ state of the atom or ion.
