oxidation Scientific  

/ ŏk′sĭ-dā′shən /

1. The chemical combination of a substance with oxygen.

2. A chemical reaction in which an atom or ion loses electrons, thus undergoing an increase in valence. Removing an electron from an iron atom having a valence of +2 changes the valence to +3.

3. Compare reduction
