Physical Properties of Group 2 Elements
  1. Electron Arrangments
    1. Highest 2 electrons in 's' subshell
      1. Down the group, highest energy electrons are held further out from nucleus
        1. Forms +2 ions
        2. Atomic Radius
          1. Increase in size going down the group
          2. Melting Point
            1. Group 2 elements are all metals so they have high melting points
              1. Magnesium is an anomaly, lowest melting point of Group2
              2. Ionisation Energies
                1. Group II elements forms +2 ions in all reactions
                  1. Both 1st and 2nd ionisation energies decrease down the group
