      - Charge density of metal cation
      - Differences in q will have bigger effect than differences in r
    - - Electrically neutral

    - - LE of an ionic crystal is the energy evolved when 1 mol of the solid ionic compd 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
