Developed with a central theme and by a teaching community 

• Emphasising the particulate nature of matter and more specifically how structure affects properties, Dr. Tro consulted–on everything from content and organisation to art and pedagogy–with a community of instructors who teach their general chemistry courses with an atoms-first approach
• Unlike in other atoms-first texts, the theme of structure affecting properties is carried throughout the entire book, including the topics commonly taught in the second half of the course, in order to consistently emphasise the theme and present topics in a logical progression. 
  • Art has also been carefully selected to best demonstrate visually the relationship between microscopic and macroscopic. 
  • Over 250 instructors teaching with an atoms-first approach were involved in the development of the text including:  
    
• 2,000 students were also involved in development by class testing chapter and providing detailed reviews. 
  
• 150 reviewers
• 75 class testers
• 50 focus group participants

• Conceptual Connections reinforce conceptual understanding of the most complex concepts in each chapter while the consistent step-by-step framework within the in-chapter worked examples encourages students to think logically through the problem-solving process
• Each chapter includes several Conceptual Connections, in which students are asked to think about key concepts and solve problems without doing any math.
• Tro’s four-step “Sort, Strategise, Solve, and Check” approach helps students connect the concept of the problem to its solution by developing an explicit conceptual plan for each problem. This method helps students understand where to start when given a problem and to think through the solution rather than simply formula hunting based on the given information.
• Two- and three-column example formats help students to understand the logic and purpose of each step in the problem-solving process as well as the details of its implementation. Tro’s conceptual plans map out problems for students and, in many cases, also apply the same methodology to another problem in a side-by-side format.
• Some topics can be covered with just one example (with the explanation in the left column and the worked-out example in the right column), while other topics are best covered by having two side-by-side examples (with the explanation in the left column and two side-by-side examples in the center and right column). Three-column examples typically show two similar but slightly different approaches to the same concept.
• Self-Assessment Quizzes are located at the end of each chapter. Tro's Self-Assessment Quizzes contain 10-15 multiple-choice questions that are similar to those found on the ACS exam on other standardised exams.

Visualising and understanding chemistry:

• Multipart images include symbolic, macroscopic, and molecular perspectives that are fundamental to visualising and understanding chemistry.  
• Tro’s 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 behaviour of atoms and molecules. 
• Illustrations include extensive labels and annotations to direct student attention to key elements in the art and promote understanding of the processes depicted.
