What Lattice enthalpy as a measure of ionic bond strength means in Chemistry A-Level, as defined for OCR.
Definition of Lattice enthalpy as a measure of ionic bond strength
Check what you remember
Read the wording for your board, then hide it and explain Lattice enthalpy as a measure of ionic bond strength in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The magnitude of ΔLEH measures how strongly the ions are held in the giant ionic lattice, so a more negative value means stronger ionic bonding.
