Excellent condition 5 lbs 11 ozs (e Book) More than atoms first--atoms focused. The authors, who have more than two decades of combined experience teaching an atoms-first course, have gone beyond reorganizing the topics. They emphasize the particulate nature of matter throughout the book in the text, art, and problems, while placing the chemistry in a biological, environmental, or geological context. The authors use a consistent problem-solving model and provide students with ample opportunities to practice. Please note that this version of the ebook does not include access to any media or print supplements that are sold packaged with the printed book.
