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 ...

One had a crystal structure of two sodium chloride molecules for every 17 water molecules. That one formed at a temperature of about minus 100 degrees Fahrenheit and a pressure of 5,000 times the ...
