Isabel Thomas and her illustrator, Sara Gillingham, have forged a handy reference book for teenagers (not children.) The book is well organized, explains the periodical table, breaking it into manageable sections. There is a great deal of information packed into this colorful book: fun facts, how elements got their name, how they are used or impossible to find in nature, etc. However, after awhile, things begin to blend together (not the elements), but the facts and details become overwhelming.
