- Metals can be arranged in order of how reactive they are.
- Metals high in the reactivity series can displace metals lower down.
- Metals at the top of the series lose electrons easily and form positive ions.
- Here are the main metals in the reactivity series starting with high reactivity: - K - Potassium - Na - Sodium - Ca - Calcium - Mg - Magnesium - Al - Aluminium - Fe - Iron - Pb - Lead - Cu - Copper - Hg - Mercury - Ag - Silver - Au - Gold
