Definition of ionic charge and radius
Check what you remember
Read the wording for your board, then hide it and explain ionic charge and radius in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
Higher ionic charges and smaller ionic radii increase the magnitude of lattice enthalpy by strengthening electrostatic attraction between the oppositely charged ions.
