What charge and radius means in Chemistry A-Level, as defined for AQA.
Definition of charge and radius
Check what you remember
Read the wording for your board, then hide it and explain charge and radius in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Lattice strength rises as the charge on the ions rises and as the ionic radii fall, because the attraction depends on charge density.
