- A. Have close packing
- B. Have low empty spaces
- C. Becomes less tight
- D. Have strong electrostatic forces
Explanation
Lattice energy is inversely proportional to size of ion. Charge/Size define lattice energy.

About Lattice Energy
Lattice energy describes the energy released when gaseous ions form one mole of an ionic solid, or the energy required to separate that solid into gaseous ions, depending on the convention used. Its value depends mainly on ionic charge and radius and is calculated through Born-Haber cycles.
