CHEMICALNOMENCLATURE INTRODUCTION Chemical nomenclature is the system of names used to distinguish compounds from each other and the rules needed to devise these names. The most modern nomenclature system uses rules that follow the recommendations of the International Union of Pure and Applied Chemistry
to which a compound belongs. In Chemistry 68/60,thrce nomenclature categories are studied - ionic compounds, binary molccular compounds, and acids.To master chemical nomenclature.it is necessary to memorize the names,formulas and charges of polyatomic ions (there are hundreds of polyatomic ions- you are responsible for the ones assigned by your professor. It is also necessary to memorize the charges on the fixed charge ions. Review the rules on chemical nomenclature in Chapter Sof your texthook.
