Renowned author team, Steve and Susan Zumdahl have for decades focused on helping students build critical-thinking skills while learning to “think like chemists.” This focus on conceptual understanding and strong problem-solving orientation provides students the building blocks towards gaining mastery. In this third edition of CHEMISTRY: AN ATOMS FIRST APPROACH, Steve and Susan Zumdahl, with new co-author Don DeCoste, place special emphasis on the fluidity of topics, guiding students through the concept of molecules, structure and bonding to more complex materials and their properties. This text is enhanced with interactive resources available in OWLv2, a powerful online learning system with richly dynamic problems and newly enhanced content that features a wider range of quality feedback and point-of-use remediation.
