The removal of oxygen or addition of hydrogen.

The gain of electrons or hydrogen, or the loss of oxygen, by a molecule, atom or ion; the donation of an electron to a molecule.

Occurs when oxygen is removed from a compound (or when an atom or ion gains electrons).

A chemical reaction in which ions gain electrons to reduce their positive valence.

The gain of electrons by a chemical species.

Gain of electrons by an atom or molecule as occurs when hydrogen is added to a molecule or oxygen is removed. The opposite of oxidation.

removal of oxygen from a chemical compound.

 A chemical process that results in the acceptance of electrons by an electrode’s active material.
