Question

If lattice energy of naf is kx then lattice energy of mgo approximately is

Answer 1

Answer:

Explanation:

A compound has higher lattice energy if it's ions have smaller size and greater charge

Li cation is smaller than Mg cation => +1 for (LiF)

Fluoride anion is smaller than oxide anion => +1 for (LiF)

Mg cation has greater charge than Li cation => +1 for (MgO)

Oxide anion has greater charge than fluoride anion => +1 for (MgO)
