This companion to the category best-selling book The Elements is a beautiful card deck featuring all 118 elements in the periodic table. One element per card appears as a full-size image on the front and fascinating information about the element on the back. This is the most detailed and beautiful set of reference cards ever produced on the subject of the periodic table. The front side of each 127 x 127 mm card shows a full-size photographic image of the element, while the reverse gives scientific information including atomic weight, density, melting and boiling point, valence and the percentage of the element found in the universe, the earth's crust, the oceans and in man.
