General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a much more dangerous place. Although there are other types of compounds, for this lesson we will concentrate on ionic formulas, both binary and polyatomic and binary molecular formulas.
Objectives: 1. Given a chemical formula, identify it as an ionic or molecular type of chemical compound, write the IUPAC name (no common names). 2. Given the IUPAC name of an ionic or molecular compound, write the chemical formula associated with it.

Discussion: At this point in the course you have used the periodic table as your reference for where the elements are located. The Periodic Table will be the most important tool to have on hand for this exercise and for every quiz, exam and most homework problems you do. Write on it, use color for regions, and individualize it for yourself. You have been learning how to combine metal ions with nonmetal ions to write ionic compounds in lecture. In this exercise you will be learning how to name the formulas for many of these compounds, along with many of those you have been using in the previous experiments, and examples.
Communication skills are important in any field, and the language of chemistry has a vocabulary of its own. In the medical services it is essential to communicate clearly and effectively. When transferring responsibility for a patient to another person, or asking the doctor or dentist for the medication
