What lattice enthalpy means
Lattice enthalpy describes the energy change when an ionic lattice forms from gaseous ions or when it is separated back into gaseous ions. Stronger electrostatic attraction gives a larger magnitude of lattice enthalpy and usually a higher melting point.
Step-by-step lessons on Edexcel A Level Chemistry Lattice energy and Born-Haber cycles. Each one builds up to exam-style questions. Build confidence with atomic structure, bonding and moles calculations early on, since these underpin the more demanding organic mechanisms, equilibrium and practical-analysis topics that dominate Year 2.
