Seventh edition! If you liked the previous editions of this one-term chemistry textbook, as I did, you will like this edition. And it has been improved, though one might think wisdom would have been to leave well enough alone. This edition hones the outstanding clarity of presentation and emphasis on how to solve problems. A special feature of the latter is the use of interesting graphics to clarify the pertinent steps and concepts involved, say, in stoichiometry. Others may be intrigued with the unique flowchart for nomenclature (p 280) that would appeal to students exposed to programming or who are comfortable with computers, surely a sizeable majority of students. Another special feature: focus boxes in the text that provide an effective emphasis of concepts and their applications/significance ("Calcium in the Body" comes after a section called "Predicting Chemical Reactions"). The margins also are used effectively for assignable Activity (Activity 2-4, how much do you weigh? in a section on significant digits) that provide an immediate enforcement instead of waiting for useful exercises at the end. Other margins are used for a Chemistry in Action series, also numbered, that call for simple experiments that the student can perform, typically with household chemicals and with explicit instructions and precautions. These units provide a chance for individualized or group activities. The enforcement actions/activities in context are surely effective pedagogy, but not the only examples in this book. The success of the first six editions surely is based upon the quality and clarity of the presentation, the author's gift in presenting important material in a clear, interesting way. I also liked the order of topics presentations: Gases and Gas Laws comes after Atomic Structure and the Periodic Table, and after Bonding; the 17th--and last chapter--is an interesting one on biochemistry. A set of useful appendices and a useful glossary complete the text. I tested the Index, and it worked for me. A full range of supplements is available: Instructor's Manual; for Text and Lab, Test Bank, Microtest Computerized Test Bank, Study Guide, Laboratory Experiments, Seventh Edition.
