lattice-energy

Lattice Energy - The energy released when gaseous ions combine to form an ionic solid, or equivalently, the energy required to break the ionic crystal into its constituent ions.

  • Often estimated using coulombs_law based frameworks, though real ions have finite sizes and polarisation effects.
  • Appears in the born-haber-cycle, connecting ion formation, electron affinities, and enthalpy changes.
  • Higher lattice energy usually indicates a stronger ionic_bond, leading to higher melting points and lower solubility in some solvents.

Note

Lattice energy trends help rationalise why smaller ions with higher charges tend to form more stable, less soluble ionic crystals.
