|Acknowledgments

In this edition, it is our pleasure to see Neil Jespersen take on the role of lead author. He has more than proven himself in his role as a contributing author on the last edition and we are confident in his ability to carry the text forward into future editions. It is also our pleasure to welcome Alison Hyslop to the author team. Her expertise in physical inorganic chemistry and her dedication to teaching and to her students has been a significant asset toward the development of this book.

We express our fond thanks to our spouses, June Brady, Marilyn Jespersen, and Peter de Rege, and our children, Mark and Karen Brady, Lisa Fico and Kristen Pierce, and Nora, Alexander, and Joseph de Rege, for their constant support, understanding, and patience. They have been, and continue to be, a constant source of inspiration for us all.

We deeply appreciate the contributions of others who have helped in preparing materi- als for this edition. In particular, Duane Swank, of Pacific Lutheran University, for his help in preparing the Answer Appendix and Solutions Manuals, and Conrad Bergo of East Stroudsburg University, for reviewing the answers and solutions for accuracy. We thank John Murdzek for his thoughtful suggestions regarding various aspects of the text. We would also like to thank the following colleagues for helpful discussions: Gina Florio, Elise Megehee, Richard Rosso, Joseph Serafin, and Enju Wang.

Is it with particular pleasure that we thank the staff at Wiley for their careful work, encour- agement, and sense of humor, particularly our editors, Nicholas Ferrari and Jennifer Yee.

The girl listening to music on her iPod probably isn’t thinking much about chemistry, but if it were not for the inventions made possible by chemical discoveries there would be no music to fill her spare time. In this chapter you begin your study of a science that affects your life every single day. As you progress through your chem- istry course, we hope you enjoy learning about how the properties of atoms and molecules affects the world in which you live. Granger Wootz/Getty Images, Inc.
