NomenclatureThe purpose of this section is to specifically address the issues of chemical nomenclature. Several methods or systems for naming chemicals have been developed over the years. initially, each chemical got its own name based on whatever feature (or whim) impressed people at the time. In the late 1700s, Antoine Laurent Lavoisier proposed a systematic nomenclature in which compounds were named according to the elements contained in them. That basic approach has been kept over the years even though different methods have been developed to achieve it. In this section you will be responsible for using several types of names: simple, Latin, Stock and prefix. You will also need to know when to use these different types of names. Simple names are used for ionic compounds (and some covalent compounds) where only one compound is made from those elements. Latin names are used for ionic compounds (and some covalent compounds) where more than one compound is made from those elements. Stock names are used for ionic compounds and covalent compounds where more than one compound is made from those elements. (Actually, Stock names can also be used for ionic compounds and covalent compounds where only one compound is made from those elements, but the Stock names are the same as simple names in those cases.) Prefix names are used for covalent compounds. (There are a few cases where prefix names can be used for ionic compounds, but you have to know the specific cases where that is permissible if you want to do that.) As you work through the pages in this section, you will have to pay attention to the type of compound in order to determine the proper type (or types) of name to use for each compound.
