Ore
A mineral that contains enough metal or metal compound to make it economically viable to extract that metal
Oxidation
The loss of electrons from a substance or the addition of oxygen to a substance
Product
A substance made during a chemical reaction
Reactant
A substance present at the start of a chemical reaction
Reactivity series
An arrangement of metallic elements with the most reactive first and the least reactive last
Redox reaction
A reaction in which both oxidation and reduction are occurring
