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 ...

The film provides an introduction to crystal growth and structure, focusing on sodium chloride (common salt) as a primary example. It details the process of crystal formation under a microscope, ...

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 ...

Elements bond in fixed ratios and so can be represented by a chemical formula. For example, sodium chloride has the same number of sodium ions and chloride ions, so its formula is NaCl ...
