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 ...

This helps to visualise the structure. A two-dimensional model for the ionic lattice in sodium chloride A 2D model shows the arrangement of one layer of ions but it does have a major additional ...

form a regular lattice structure in which oppositely charged ions are strongly attracted to each other. Sodium chloride is an ionic compound. The table shows some limitations of different models ...
