What do the numbers on the periodic table mean? What were the halogens again? If these questions sound familiar, you are probably a beginner chemistry student. And like many new chemistry students, you may sometimes get tangled up in the details. This book clearly explains many of the concepts that confuse new chemistry students including how to read and understand the periodic table, physical versus chemical changes, the states of matter, and the differences between atoms, molecules, mixtures, and compounds. The different ways that atoms combine to form molecules are reviewed, and the naming of simple molecules is taught in depth. Diagrams and problems are included to test your understanding of these concepts.
This book should be most useful to the beginning student of chemistry at any grade level, though most ideally high school level or the very beginnings of college.
Chemistry is a challenging subject. You must have a good grasp of the fundamentals before you can progress to more advanced topics. This book reviews the basic concepts you will encounter in introductory chemistry. It is not a substitute for a textbook; it is meant to be a refresher, to help you with concepts that were taught too quickly or not recently. Do not skip the problem sets! They have been designed to enhance your understanding and your retention. In a test, the most important thing is to get the right answer, but studies have shown that the most meaningful learning occurs when students try and sometimes fail to answer questions. Thinking the answer through, and trying to understand (and correct) the mistake gives you a firmer grasp on the concept. I sincerely hope this book helps you in your chemical education, and if it is too basic, then I hope that you find the appendix an interesting reference.
