  • Reaction With Oxygen
    • Group 2 Alkaline Earth Metals
      • Reaction With Water
        • Group 2 Metals react with Water
        • Forms an alkaline Hydroxide (OH)
        • Redox Reaction
        • Forms Hydrogen Gas (H2)
        • Reactions become more vigorous with metals further down the group.
          • Reactivity increases down the group
      • Group 2 Oxides react with Water
        • Forms Metal Hydroxides
        • Hydroxide ions make these solutions strongly alkaline
        • The oxides form more strongly alkaline solutions as you go down the group.
          • The hydroxides get more soluble
      • Uses of Group 2 Compounds
        • Magnesium Hydroxide
          • Used in indigestion tablets as antacids
      • Group 2 Elements form 2+ Ions
        • Group 2 elements have two electrons in their outer shell
        • Lose two electrons in order to obtain a full outer shell
    • Forms a Metal Oxide
    • Forms a White Precipitate
    • Group 2 Metals burn in Oxygen
    • Redox Reaction
  • Reaction With Dilute Acids
    • Group 2 Metals react with Dilute Acids

    • Forms Salt and Hydrogen (H2)
    • Reactivity increases down the group
  • Calcium Hydroxide
    • Used in agriculture to neutralise acidic soils
