The Periodic Table Playing Cards consists of two packs of regular playing cards with one element from the Periodic Table Elements on each card. The cards show the name of the element in English, French and Spanish, the atomic number, the mass, the category, melting and boiling points, period and group, natural state and common usages. These are playing cards, but most importantly they are an excellent resource for any one interested in science!
