The Disappearing Spoon and Other True Tales of Madness, Love, and the History of the World from the Periodic Table of the Elements
The pages around the main content are: Introduction, Acknowledgments and Thanks, Notes and Errata, Bibliography, Index, and The Periodic Table of the Elements.
He does a really good job of linking things in the text to the Notes and Errata and that makes it more interesting. It's a very thorough Index, and having the perodic table on the back page is helpful.
I never took chemistry or taught it to myself, but I do read papers and magazines, so I knew about a quarter of the elements and their indicators. This book not only tells about the elements, how they were found, and how they work, but about the people who found them, how they worked together, and how they changed the world.
I really liked this book. He only lapses into chemistry major mode (which he wasn't) a couple times; the rest of the book is very interesting.
