Principles of Chemistry: A Molecular Approach, 4th edition

For 2-semester courses in general chemistry

A streamlined approach develops expert problem solvers and critical thinkers

Principles of Chemistry: A Molecular Approach introduces core concepts without sacrificing rigor. Nivaldo Tro presents chemistry visually through macroscopic, molecular and symbolic multi-level images to help students see connections between chemistry and the world around them. Throughout this student-friendly text, active learning tools engage students in becoming expert problem solvers and critical thinkers.

The 4th Edition pairs pedagogical innovation with insights from learning design and educational research to create an active, integrated and easy-to-use framework.

Hallmark features of this title

• 4-step problem-solving approach (Sort, Strategize, Solve, Check) connects concepts to the problem and solution by developing a conceptual plan for each problem.
• Multipart images help students see the relationship between the formulas they write down on paper (symbolic), the world they see around them (macroscopic), and the atoms and molecules that compose the world (molecular).
• Abundant molecular-level views show students the connection between everyday processes visible to the eye and the behavior of atoms and molecules.
• Streamlined coverage of necessary general chemistry topics provides instructors with a text that covers only the topics that they needs. At 19 chapters, this text has no separate nonmetals, metals or coordination compounds chapters.

New and updated features of this title

• Missed This? feature appears in the end-of-chapter Self Assessment Quizzes and in each odd-numbered Problems by Topic exercise and provides sections to read to help students remediate where necessary.
• Chapter 5 provides topically focused coverage. Chemical Reactions and Solutions have been divided into two separate chapters (now Chapters 4 and 5): 1 on chemical reactions (including stoichiometry) and another on solutions (including aqueous reactions). This new organization allows a sharper focus in each chapter and reduces the cognitive load for students.
• Extensively updated art program better directs students' attention to key elements in the art and promotes understanding of the processes depicted. Dozens of figures in the 5th Edition were reviewed by learning design specialists to ensure they are clearly navigable for students and now include more helpful annotations and labels to help readers focus on key concepts.
