Oxidation & Reduction
Metals can gain oxygen atoms and become oxides. This is called oxidation, e.g. iron + oxygen = iron oxide. This is what happens when iron rusts.
Oxidation of metals is called corrosion.
Metal oxides can lose oxygen and become metals. This is called reduction. Reduction takes place when iron is extracted from its ore.
If iron is not protected it will corrode by reacting with oxygen from the air.
