Nomenclature #1

I learned how to name different kinds of binary compounds in this unit of nomenclature. Type 1 contains a metal and nonmetal. The metal (cation) has a constant charge. Type 2 generally come from the d block, and don't give away the same amount of electrons. Use roman numerals to indicate the charge of the first element named. For example, CuCl would be named as copper(I) oxide. Type 3 are two nonmetals. You would use a prefix to indicate how many of the element. For example, PCl5 would be named as phosphorus pentachloride.
