My goal with this book is to give you the really essential information and concepts that you would face in a first semester chemistry class in high school or college. I’ve omitted a lot of topics found in a typical chemistry textbook. This book is designed to give you the bare essentials. Remember, this is a light treatment. If you want more, many other books are available. My favorite, naturally, is Chemistry For Dummies. I understand the author is really a great guy.
