The lattice arrangement continues in three dimensions. This is why solid ionic compounds form crystals with regular shapes.

This video explains ionic bonding. An ionic compound is made up of charged particles, called ions. It has a giant lattice structure, with strong electrostatic forces of attraction.

Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ... Because of its ionic bonding the material is an electronic insulator at room temperature and is transparent in ...
