Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

In a sodium chloride crystal, the sodium and chlorine ions arrange themselves in a repeating pattern known as a lattice.

Halite, commonly recognized as table salt (NaCl), often forms transparent, cube-shaped crystals due to the orderly arrangement of sodium and chloride ions in its lattice. Similarly, galena (PbS ...

As the attractions from the water molecules and their motion pulls the ions apart, the sodium chloride crystal dissolves. The positive areas of the water molecules surround the negative Chloride ions.

A dot and cross diagram for sodium chloride suggests that it is made up of pairs of sodium and chloride ions. It is not. A 3D construction model shows how the ions are arranged in a lattice structure.
