Compare table salt and sugar.

The chemical formula for sucrose is C12H22O11, which means that each sucrose molecule has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms. The atoms come from one glucose monomer plus one fructose monomer. These two monosaccharides are linked by a glycosidic bond. The chemical formula for table salt, otherwise known as sodium chloride, is NaCl. Knowing that sodium chloride is a salt as opposed to a molecule like sucrose, this chemical formula tells us that table salt is a lattice structure of sodium cations and chloride anions arranged in a 1: 1 ratio. Sodium chloride is held together by hydrogen bonds, not molecular bonds.
