Place the following in order of increasing magnitude of lattice energy
CaO, MgO, SrS

Lattice energy is defined as a measure of the energy contained in the crystal lattice of a compound. It can be seen as the energy that would be released if the component ions were brought together from infinity.

Lattice energy depends on size of the ions. The smaller the ions, the greater the lattice energy. When we look at all the actions in the substances listed, we will notice that the order of decrease in cation size is Sr^2+>Ca^2+>Mg^2+. The lattice energy increases in the this order.

Hence MgO will have the greatest lattice energy of all the species listed.

The order of increasing magnitude of lattice energy is; SrS < CaO < MgO

Definition:

Lattice energy is simply defined as the energy required to convert one mole of an ionic solid into gaseous ionic constituents.

Lattice energy is dependent on the size of the constituent atoms.

The greater the distance between the nucleus of the constituent atoms, the lesser is the lattice energy.

Therefore, the order of increasing magnitude of lattice energy is;

SrS < CaO < MgO
