- Names and symbols of the Elements. Naming of chemical substances begins with the names of the elements. The discoverer of an element has traditionally had the right to name it, and one can find some interesting human and cultural history in these names, many of which refer to the element's properties or to geographic locations.
- Naming the binary molecules. The system used for naming chemical substances depends on the nature of the molecular units making up the compound. These are usually either ions or molecules; different rules apply to each.
- Naming the ions. An ion is an electrically charged atom or molecule— that is, one in which the number of electrons differs from the number of nuclear protons.
