• Among LiF and MgF2, which one has more lattice energy? Lattice enthalpy of two salts can be compared by using Born–Lande equation (one of method) as,So, greater the charges of cation & anion, higher will be the lattice energy of the corresponding salt. Again, smaller the ionic radii of cation and anion, higher will be the lattice energy.

• on the lattice energy of a point ion model with various choices for the form of ion core repulsion and cor- rections for polarizability. The best approach to date appears to be the use of the shell model to accom- modate polarization and a set of empirical potentials matched to elastic and dielectric properties (Catlow 1977).
• From these, we can calculate the lattice energy Φ (in eV) of silicon as a function of the number density ρ (in 1/Å 3), for diﬀerent crystal structures, as shown in Fig.1. The structure with the lowest energy is DC. The equilibrium lattice constant a 0 corresponds to the number density that gives the minimum of the Φ(ρ) curve.
