Chemistry has a rich history, including ancient theories on the nature of matter and recipes for converting lead into gold. Modern research and applications are equally exciting. For example, models of chemical bonds explain why carbon dioxide and methane are greenhouse gases, and some of the colors we see in the Aurora Borealis. We will explore these topics as we learn about atomic structure and the periodic table, reaction stoichiometry, chemical bonds, molecular structure, and other concepts central to modern chemistry. Many of these topics are related to current health and environmental issues. For example, discussions of pH and reduction-oxidation reactions include research on the natural chemistry of surface waters.
