This illustrated periodic chart is available in three handy sizes: wall size for classroom instruction, poster size for easy lab reference, and binder size for students’ personal reference. Each element is shown in its most common state; the photos indicate appearance, metallic or non-metallic character, reactivity (by kind of storage depicted), and characteristic use (when possible). Binder version is two-sided, detailing melting and boiling points, oxidation state and more. All charts use both old and new IUPAC numbering systems, with English, Spanish, French and German notations.
