10) Lattice energy depends on the ionic size and ionic charge. Hence –
The ions with smaller size and greater charge will form the stable ionic compound.
Thus –
a) Among the given compounds – ZnS (Zn2+ and S-2) may have the greater lattice energy.
) In the similar manner , among the given compounds –
Al2O3 will have the greater lattice energy.
