Enthalpy-level Born–Haber cycle for sodium chloride: sublimation +107, ½ bond enthalpy +122, ionisation +496, electron affinity −349, lattice −787 and ΔfH° −411 kJ mol⁻¹, with the sum shown. ## What the template shows - Hess's law around the formation of an ionic solid from its elements (kJ mol⁻¹, energy to scale) - ½ Bond enthalpy of Cl₂ - First ionisation energy of Na - Electron affinity of Cl - Lattice enthalpy - Going round the cycle, the enthalpy changes add up to ΔfH°(NaCl): the route through gaseous ions equals the direct one. - The lattice enthalpy cannot be measured directly; it is the term that closes the cycle. - Forming the lattice (−787) more than pays for making the ions (+496 − 349): that is why NaCl is stable even though Na⁺ + Cl⁻ in the gas are higher than the atoms. - Sign convention: lattice enthalpy here is for forming the solid from gaseous ions (exothermic); for breaking it up it is +787 kJ mol⁻¹. - Every part of this figure is editable · sources on the template card Drawn with 26 shapes – every one editable in MolDraw. ## Sources - [Housecroft & Sharpe, Inorganic Chemistry, 5th ed., Pearson 2018, ch. 6](https://openlibrary.org/isbn/9781292134147) Textbook - [Atkins, de Paula & Keeler, Atkins' Physical Chemistry, 11th ed., OUP 2018, ch. 2](https://openlibrary.org/isbn/9780198769866) Textbook - [NIST Chemistry WebBook: sodium chloride](https://webbook.nist.gov/cgi/cbook.cgi?ID=C7647145) Database ## How to use this template 1.
