Those wishing to add to their collection of guides to the elements may want to examine John Emlsey's Nature's Building Blocks: An A-Z Guide to the Elements or Theodore Gray's more recent The Elements: A Visual Exploration of Every Known Atom in the Universe for similar information and presentation.
