For two-semester or three-quarter courses in General Chemistry. Tro provides students the support they need early so they can tackle challenging topics later. He does this by building on what students already know. The author's goal in writing this book is to deliver the depth of coverage faculty want with the accessibility and clarity that students need for success. Nivaldo J. Tro's Chemistry: A Molecular Approach explains difficult chemical concepts in a concise and clear student-centered manner while also providing faculty with the flexibility to go more deeply into many key, often neglected topics, such as electron diffraction, molecular orbital theory, and free-energy changes under non-standard conditions. Chemistry is presented visually throughmulti-level images (macroscopic, molecular and symbolic representations), which helps students see the connections among the formulas (symbolic), the world around them (macroscopic), and the atoms and molecules that make up the world (molecular). Every aspect of this book focuses students on recognizing that the behavior of matter is based on the behavior of atoms and molecules.
