Why do ionic compounds form giant structures rather than small molecules?
The electrostatic forces act in all directions, so many ions attract together
The ions share pairs of electrons with every one of their nearest neighbours
The ions are held together by weak forces of attraction between molecules
The ions are too large to be able to form molecules of only a few particles
