  • AS CHEMISTRY
    • GROUP 2
      • REACTIONS
        • WITH OXYGEN, THEY FORM OXIDES MO.
          • SrO- Red flame
          • CaO-Red flame
          • BaO-Pale green flame
          • MgO-White light
        • WITH WATER, THEY FORM R(OH)2+ H2
          • Mg
            • H2O(G)- MgO +H2
            • H2O(L)- Mg(OH)2+ H2
          • Ca(OH)2+H2
          • Sr(OH)2+H2
          • Ba(OH)2+H2
          • BERYLLIUM DOESN'T REACT WITH WATER
        • WITH CHLORINE
          • THE OTHERS FORM IONIC CHLORIDES WITH THE FORMULA MCl2
          • BERYLLIUM FORMS A COVALENT ANHYDROUS CHLORIDE
          • ALL GROUP 2 ELEMENTS REACT WITH CHLORINE WHEN HEATED
        • OXIDES WITH WATER
          • BERYLLIUM OXIDE DOESN'T REACT WITH WATER
          • Mg(OH)2
          • Ca(OH)2
      • IONISATION ENERGY
        • Decreases down the group, as electrons removed will be further from the nucleus
