Oxidation is the process when oxygen combines with an element, changing the appearance of the element. When iron reacts with oxygen and changes to rust, this is an example of oxidation.
Oxidation is a chemical reaction that takes place when oxygen reacts with another element. Oxygen is very strongly chemically reactive. The most familiar type of oxidation is when iron reacts with oxygen to create rust (figure 8). Minerals that are rich in iron break down as the iron oxidizes and forms new compounds.
