Specification 5.2.1.2, 5.2.1.3 · Paper 3
Revise: Ionic Bonding MechanismsThe resulting oppositely charged ions attract one another. This strong electrostatic attraction is ionic bonding. Electron transfer explains how the ions form; the attraction explains how they are held together.
The strong electrostatic attraction between oppositely charged ions, acting in all directions throughout an ionic lattice.
Electron transfer forms the ions; ionic bonding is the electrostatic attraction between them.
Describe ionic bonding as strong electrostatic attraction between oppositely charged ions, acting in all directions throughout the lattice.
When identifying an ionic structure, use the labelled ions and their charges as evidence. Different colours alone do not establish ionic bonding.
