Extraction of Metals & Reduction

Extraction of metals and the reactivity series. The most reactive metals are at the top of the series The tendency to become oxidised is thus linked to how reactive a metal is and therefore its position on the reactivity series Metals higher up are therefore less resistant to oxidation than the metals placed lower down which are more resistant to oxidation
