Sodium chloride (NaCl) models can show the structure of this ionic compound in a variety of ways, including:
-
Ball-and-spoke modelThis model shows two interpenetrating face-centered cubic lattices of sodium and chloride ions. The model is mounted on a clear acrylic base and the balls are 22 mm in diameter.
-
Molecular modelThis model can be made with Molymod components and can show 13 sodium atoms and 14 chlorine atoms. The model can be extended to any size and can also represent other chemical structures.
-
Crystal structureThe structure of sodium chloride is best thought of as a face-centered cubic array of anions with an interpenetrating face-centered cubic cation lattice. Each ion has a local octahedral geometry and six coordinates.
Sodium chloride is a typical ionic compound made of sodium and chlorine ions that are bound together by covalent bonds. It is a white crystalline condiment and road de-icer.
