The higher lattice energy corresponds to

Question

The higher lattice energy corresponds to (A) MgO (B) CaO (C) SrO (D) BaO

Tardigrade Admin · Accepted Answer

Lattice energy propto charge of ion propto (1/ textsize of ion) On moving downward, the size of alkaline earth metals increases due to increase in number of shells. Thus, Mg has the smallest size. Hence, lattice energy is higher for MgO.

Q. The higher lattice energy corresponds to

MgO

CaO

SrO

BaO

Lattice energy $\propto$ charge of ion $\propto \frac{1}{size of ion}$ On moving downward, the size of alkaline earth metals increases due to increase in number of shells. Thus, Mg has the smallest size. Hence, lattice energy is higher for $M g O$ .

Lattice energy ∝ charge of ion ∝size of ion1​ On moving downward, the size of alkaline earth metals increases due to increase in number of shells. Thus, Mg has the smallest size. Hence, lattice energy is higher for MgO.
