After picking this book up at a discount store, I was disappointed to see so much incorrect and confusing information in only the first 10 pages. I didn't really want to read past the introductory chapter after the author incorrectly listed how many electrons fit in each of the energy shells. I figured that maybe some of the confusion was due to the fact that the author uses British-English, and I'm American, but some mistakes couldn't be chalked up to that. It was enough to make me put the book down. Not sure I would recommend.
