Forms of Sodium Chloride

Sodium chloride is the most common salt, the common table salt used for the seasoning of food. The images above are grains of table salt from a salt shaker, taken at 50x and 200x. Those images show the tendency to form a cubic structure, a symmetry borne out in the atomic level structure of the salt crystals. It occurs commonly in the mineral form, halite, also called rocksalt.
