Make chemistry relevant to students

Now in its fifth edition, Introductory Chemistry continues to foster deep engagement in the course by showing how chemistry manifests in students’ daily lives. Author Nivaldo Tro draws upon his classroom experience as an award-winning instructor to extend chemistry from the laboratory to the student’s world, capturing student attention with relevant applications and a captivating writing style.

This program provides a better teaching and learning experience—for you and your students. It will help you to: 
• • Enable deep conceptual understanding: Several new Conceptual Checkpoints and Self- Assessment Quizzes help students better grasp key concepts.
• Foster development of problem-solving skills: A step-by-step framework encourages students to think logically rather than simply memorize formulas. Additional worked examples, enhanced with audio and video, reinforce challenging problems.  
• Encourage interest in chemistry: The inclusion of concrete examples of key ideas throughout the program keeps students engaged in the material.

Personalize learning with (optional) MasteringChemistry®: This data-validated online homework, tutorial, and assessment program helps students quickly master concepts, and enables instructors to provide timely intervention when necessary.


Enable deep conceptual understanding

Conceptual Checkpoints reinforce conceptual understanding of the most complex material. Strategically placed throughout each chapter, they prompt students to think about concepts and solve problems without doing any math. Answers and explanations appear at the end of each chapter.

NEW! The fifth edition includes more than 20 new Conceptual Checkpoints, focused on visualizations and drawing as requested by reviewers. These additions reinforce the program’s focus on helping students understand all relevant concepts.

NEW! Key Learning Outcomes that correlate to the Chemical Skills and Examples in the end-of-chapter material and to the content within MasteringChemistry have been added to each chapter section. Each section (after the introductory sections) includes at least one learning outcome summarizing the key learning objective to help students focus and assess their progress.

NEW! Chapter Self-Assessment Quizzes at the end of each chapter provide opportunities for students to assess what they’ve learned. Each quiz consists of 10–15 multiple-choice questions similar to those found on standard exams.

NEW! 3-4 Questions for Group Work have been added to the end-of-chapter problems in each chapter to facilitate guided-inquiry learning both inside and outside the classroom. 

Multipart molecular images depicted through Macroscopic, Microscopic, and Symbolic perspectives enable students to better visualize, and thus understand, chemistry.
• These multipart images help students to see the relationships among the formulas they write down on paper (symbolic), the world they see around them (macroscopic), and the atoms and molecules that compose that world (molecular).
• Abundant molecular-level views reveal the connections between everyday processes visible to the eye and the activities of atoms and molecules. 
• Extensive labels and annotations for each illustration direct students to key elements in the art and help them to understand the processes depicted.

Three-part visual images include a photograph of a real-world object or process, a depiction of what is taking place on the molecular level (either superimposed or shown as a magnified breakout), and a representation using chemical formulas. This three-tiered view helps students to visualize and understand key concepts.
In addition to structural formulas, many molecular formulas in the text are also depicted with molecular illustrations for greater clarity and vividness. In addition, macro/micro illustrations are included.
Using a hierarchical method of labeling imagesIntroductory Chemistry presents complex information clearly and concisely by making the relationships between related labels and annotations immediately evident to students.

NEW! Coverage of atomic masses has been revised to reflect recent changes made by IUPAC that introduce more uncertainty in atomic masses. The program’s periodic table itself has been revised to reflect the recommended atomic masses for “unspecified samples,” including using the value of 32.06 amu for S and 6.94 amu for Li.

Foster development of problem-solving skills 

NEW! Twenty Interactive Worked Examples instruct students how to break down problems using Tro’s “Sort, Strategize, Solve, and Check” technique in an interactive, digital format. These problems are incorporated in MasteringChemistry as assignable activities, and may also be accessed from links with the eText, the QR code on the back cover of the printed text, and the Instructor Resource Center (

In the ‘Strategize’ step for many examples, students are prompted to draw a solution map for the problem at hand. This features walks students through how to use conversion factors and equations to outline the steps needed to get from the given to the unknown.
Examples are presented in several formats that foster problem-solving skills and enable understanding.
• All but the simplest examples are presented in a two-column format. The left column acts as the instructor’s voice, explaining the purpose of each step, while the right column shows how the step is executed. This format encourages students to think critically about problem solving, and to view each step in the context of the overall plan.
• Specific procedures for solving particular types of problems are presented in a three-column format. The first column outlines the problem-solving procedure and explains the reasoning that underlies each step. The second and third columns show how the steps are implemented for two typical examples. Seeing the method applied to two related but slightly different problems helps students better understand the general procedure. 
Every worked example is followed by at least one similar, but un-worked, skill-builder exercise, which allows students to immediately test the problem-solving techniques they have just learned.

The For More Practice feature, which follows every worked example, links to additional in-chapter examples and end-of-chapter problems, providing opportunities for students to practice the particular skills in question. 

NEW! In-text cross-references to the math index appear throughout the program, to make sure students are aware that math help is available right at their fingertips.

Encourage interest in chemistry

In the text’s engaging chapter openers, Dr. Tro offers a specific example of the concept at hand to grab students' attention, steps back to make a more general and relatable analogy, and then delves into specifics. This style of presenting information is reinforced by Dr. Tro’s classroom experiences and is also commonly employed by other successful science writers.

Interest boxes of four types throughout the text keep students engaged in the course.
• Everyday Chemistry boxes demonstrate the importance of chemistry in everyday situations, such as bleaching your hair.
• Chemistry in the Media boxes discuss chemical topics that have been in the news, such as the controversy over oxygenated fuels.
• Chemistry and Health boxes focus on biomedical topics as well as those related to personal health and fitness.
• Chemistry in the Environment boxes discuss environmental issues that are closely tied to chemistry, such as acid rain and the ozone hole.

Nivaldo Tro is Professor of Chemistry at Westmont College in Santa Barbara, California, where he has been a faculty member since 1990. He received his Ph.D. in chemistry from Stanford University, for work on developing and using optical techniques to study the adsorption and desorption of molecules to and from surfaces in ultrahigh vacuum. He then went on to the University of California at Berkeley, where he did post-doctoral research on ultra-fast reaction dynamics in solution. Since coming to Westmont, Professor Tro has been awarded grants from the American Chemical Society Petroleum Research Fund, from Research Corporation, and from the National Science Foundation to study the dynamics of various processes occurring in thin layer films adsorbed on dielectric surfaces. He has been honored as Westmont's outstanding teacher of the year three times and has also received the college's outstanding researcher of the year award. Professor Tro lives in Santa Barbara with his wife, Ann, and their four children, Michael, Ali, Kyle, and Kaden. In his leisure time, Professor Tro enjoys mountain biking, surfing, reading to his children, and being outdoors with his family.
