State
Lattice energy is the energy needed to pull one mole of an ionic solid apart into free gaseous ions, a positive quantity gauging bond strength.
Show
Separating solid sodium chloride into gaseous Na⁺ and Cl⁻ ions requires a large, positive lattice energy.
Watch for
Some define lattice energy as energy released forming the solid, a negative value; this course uses the positive, separation-energy definition.
