This set discusses 180 molecules, both organic and inorganic, that have played an important role in human affairs. Each molecule is depicted by a structural formula and an attractive color image of a ball-and-stick model (at least they look attractive to a chemist). These pictorial representations are accompanied by a listing of physical properties, a description of how the compound is made, a discussion of common uses and hazards, and often a brief review of the compound's history. The overall result is a rather interesting way for a young person to gain an appreciation for the importance of chemistry and to better understand the role that chemical compounds play in everyday life. To index the molecules, there are three appendixes, listing the compounds by formula, elemental components, and type. Each volume contains a time line that contrasts developments in chemistry with historical events. The result--a unique way to introduce high school students to chemistry. In addition, teachers can use these books to find useful pieces of chemical background that can be incorporated into lectures and discussions. ^BSumming Up: Recommended.
