  • Nivaldo J. Tro

    Nivaldo J. Tro received his BA degree from Westmont College and his PhD degree from Stanford University. He went on to a postdoctoral research position at the University of California at Berkeley. In 1990, he joined the chemistry faculty at Westmont College in Santa Barbara, California. Professor Tro has been honored as Westmont's outstanding teacher of the year three times (1994, 2001, and 2008). He was named Westmont's outstanding researcher of the year in 1996. Professor Tro lives in the foothills of Santa Barbara with his wife, Ann, and their four children, Michael, Alicia, Kyle, and Kaden. In his leisure time, Professor Tro likes to spend time with his family in the outdoors. He enjoys running, biking, surfing, and snowboarding.

  • Updated Art Program. In addition to new and revised images throughout, every chapter opening image has been updated to better communicate the excitement and relevance of chemistry to our daily lives.

  • Updated Data. To ensure maximum relevance, all of the data relevant to today’s environmental and technological issues, such as Earth’s temperature, atmospheric carbon dioxide concentrations, rain acidity and pollution levels, have been thoroughly researched and made as current as possible.

  • Updated Interest Boxes. Molecular Thinking, Molecular Focus, Molecular Revolution, and “What If” boxes have been updated to reflect progress and current issues.

  • Revised Self-Check Questions. Every time a new concept is introduced, a multiple-choice Self-Check question gives students an opportunity to assess their understanding of that concept. To enhance student learning, self-check questions are now available in a digital environment that automatically tells students whether or not they answered correctly.

  • A New Set of Instructional and Interactive Videos. These BIG PICTURE VIDEOS, featuring Professor Tro and created specifically for this new edition, can be assigned to students outside of class to introduce important topics in each chapter. Each video encourages active learning by stopping in the middle to ask students to answer a question.

  • Two-part Visuals to Illustrate Thought Experiments. To help students make the connection between what they see and what is actually happening with atoms and molecules, the book includes innovative two-part visuals. One part is a macroscopic view of a familiar experience. The second part shows the microscopic image as a magnification window that portrays the molecular structure or reaction.

  • "Molecular Thinking" Boxes. These boxes describe everyday observations related to chapter material and ask students to explain the observation based on what the molecules are doing.

  • "Molecular Focus" Boxes. These boxes highlight a molecule relevant to the chapter, describing physical properties, structure, and uses of such compounds as calcium carbonate, hydrogen peroxide, ammonia, AZT, retinal, sulfur oxide, ammonium nitrate, and others.

  • "Molecular Revolution" Boxes. Designed to encourage further exploration, these boxes describe a timely topic of modern research.

  • "What If?" Boxes. These fascinating boxes focus on topics with societal, political, or ethical implications and conclude with open-ended questions for group discussion.

  • A Wide Variety of Exercises. Qualitative questions help students review key concepts from the chapter. Problems are quantitative or analytical, with varying degrees of difficulty, and ask students to apply what they have learned to solve problems. Points to Ponder are open-ended, essay-type questions asking students about the ethical, societal, and political implications of scientific issues. Feature Problems and Projects contain problems with graphics and short projects, often involving web-based inquiry.

  • "Your Turn" Example Problems and Exercises. By first solving an example in detail before giving students a similar problem to solve, the author provides step-by-step instruction as well as hands-on opportunities to practice solving problems themselves. Answers to "Your Turn" exercises are provided in the appendices for immediate feedback.
