Energy in the formation of a crystal lattice is _.
Correct answer: B. Released
- A. Absorbed
- B. Released
- C. Dependent on crystal size
- D. None of these
Explanation
A crystal lattice is a highly ordered repeating pattern of atoms or molecules. For example, table salt is composed of sodium and chloride ions that are formed in a repeating face-centered cubic structure.

About Lattice Energy
Lattice energy describes the energy released when gaseous ions form one mole of an ionic solid, or the energy required to separate that solid into gaseous ions, depending on the convention used. Its value depends mainly on ionic charge and radius and is calculated through Born-Haber cycles.
