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 ...

Here’s an example using sodium and chlorine ... Write the charge of each ion. Here are some other examples of dot and cross diagrams for the formation of ions in some ionic compounds ...

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.

Chemists from CNRS have synthesized and studied new compositions of materials for positive electrodes in sodium-ion batteries ...
