The reactivity series

• 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
