A 3D construction model shows how the ions are arranged in a lattice structure. These models usually use coloured balls to represent the ions. Some use sticks to show the ionic bonds.

A giant ionic lattice is a three-dimensional structure of oppositely charged ions held together by ionic bonds. A layer of ions in the ionic lattice for sodium chloride.

Electrides are something of a chemical curiosity. They are ionic materials within which electrons act as anions and they find roles in catalysis and as reducing agents in organic synthesis. They ...
