oxidation
Iron becomes rust
Oxidation is a chemical reaction in which a substance loses electrons, typically by combining with oxygen.
Iron rusting and wood burning are oxidation.
The term extends to any electron-loss reaction, even without oxygen: The oxidation of copper produces a green patina.
In everyday use, oxidation often means degradation from exposure to air: Store wine properly to prevent oxidation.
