        Giant molecular layered structure
        
        Unique properties
        
        Electrical conductor parallel to layers
        
        Soft and slippery
- - - - Non-directional
    - - Lattice energy of an ionic crystal is the energy evolved when 1 mol of the solid ionic compound is formed from its constituent gaseous ions.
      - Larger |LE|, stronger ionic bond
      - Differences in q has more effect on ionic bond strength than differences in r
  - - - Ion-dipole interactions
- - - - No. of delocalised valence electrons contributed per atom
      - Charge density of metal cation
        
        Differences in q+ have greater effect on metallic bond strength than differences in r+
