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 ...

Here’s an example using sodium and chlorine. They form ions which bond to form sodium chloride. 2. Work out how many electrons need to be transferred. 3. Draw the electronic configuration of the ...
