Lattice energy defined as the release of energy when a mole of crystalline solid is formed by the combination of opposite charged ions under standard conditions.
i) The increase in magnitude of the charge on an ion will increase the force of inter-ionic attraction and hence, the value of lattice energy will be greater.
ii) The smaller the size of ions, the inter-nuclear distance and the lattice energy will be higher.
