Back to Top. The word nomenclature simply means naming. There are many times when having names for chemicals is more convenient than having their formulas. Chemical naming falls into two main groups: that for ionic compounds formed of positive and negative ions, and that for non ionic compounds.

It is maintained by the International Union of Pure and Applied Chemistry.he word nomenclature is derived from the Latin nomen-name, calare-to call; the Ancient Greek Î¿Î½Î¿Î¼Î±ÏÎ¿ÎºÎ»Î®ÏÏÏ from ÏÎ½Î¿Î¼Î± or onoma meaning name, and equivalent to the Old English nama and Old High German namo which is derived from Sanskrit nama.
