• Metals form positive ions by losing electrons
• A metal that is high up on the series lose electrons more easily and is more reactive
• Carbon and hydrogen are useful in extracting metals from their oxides by reduction
• Aluminium is high in the reactivity series but does not react with water and has a slow reaction with acids. Aluminium has a protective oxide layer that prevents reactions
