Explanation:

you can use Born-Lande equation,

U=-(A×e^2×Z+ ×Z- ×N)\r ×(1-1/n)

here,U=lattice energy

A=madelung constant

n=Born exponent(depends on repulsion between ion)

e=charge of electron

Z+,Z-=charge of cation and anion

r=distance between cation and its neighbour anion in

space lattice
