- 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
- Mg
- 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
- WITH OXYGEN, THEY FORM OXIDES MO.
- IONISATION ENERGY
- Decreases down the group, as electrons removed will be further from the nucleus
