Lattice energy is crucial in understanding ionic compounds, which are held together by electrostatic forces in a crystal lattice. This energy is the measure of ionic bond strength, influencing melting and boiling points. Factors like ionic charges and radii affect lattice energy, which can be estimated using the Born-Haber cycle. Knowledge of lattice energy aids in material synthesis and analysis.
