Question

what is lattice energy ? draw a neat labelled digram of formation of ionic solid NaCl​

Answer 1

Lattice energy is defined as the energy required to separate a mole of an ionic solid into gaseous ions.

Lattice energy cannot be measured empirically, but it can be calculated using electrostatics or estimated using the Born-Haber cycle.

Two main factors that contribute to the magnitude of the lattice energy are the charge and radius of the bonded ions.

Terms

exothermic reactionA process which releases heat into its surroundings.

lattice energyThe amount of energy released upon formation of a crystalline ionic solid from gaseous ions.

Answer 2

Answer:

The bond formed between cation and anion and the energy is released known as Lattice energy.
