The metal atoms are losing electrons to form an ion. They are being oxidised. \(Mg(s) \to Mg_{}^{2 + }(aq) + 2e_{}^ - \) This is known as an ion-electron equation. Reduction is the opposite of ...

The method used to extract metals depends on the reactivity of the metal. The reactivity series allows us to predict how metals will react. Redox, extraction of iron and transition metals Redox ...
