It is an inorganic ionic compound, dissolving in water to give {Na}^{+} and {F}^{-} ions, and has a crystal structure similar to NaCl where both {Na}^{+} and {F}^{−} occupy octahedral coordination sites. Some nonmetals form a series of polyatomic ions with oxygen (all having the same charge): ClO-, hypochlorite; ClO 2-, chlorite; ClO 3-, chlorate; ClO 4-, perchlorate.. Sodium fluoride is an inorganic chemical compound that is a source of the fluoride ion in many applications, including dental care and radiographic imaging when it is used as Fluoride ion F-18. Ionic compounds form when positive and negative ions share electrons and form an ionic bond.The strong attraction between positive and negative ions often produce crystalline solids that have high melting points. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. As a halogen, fluorine forms a monovalent ion (-1 charge). Dust irritates the eyes and skin; inhaled dust irritates the nose, mouth and lungs. It is used in trace amounts in the fluoridation of drinking water, in toothpaste, in metallurgy, and as a flux, and is also used in pesticides and rat poison.
