Much more than a simple chart, the periodic table of elements identifies and categorizes chemical elements. But what exactly is an element? What do the numbers on the table signify? And how are the elements arranged? When you dig into these 48 Knowledge Cards, you’ll have many more questions. (But don’t fret: you’ll have the answers, too.) The front of each card delivers a quiz question (e.g., What makes the periodic table “periodic”? or What are the three primary types of atomic bonds?). On the back is a concise, easily digestible response.

The Elements covers everything from the ABCs of atomic structure to the KLMNOPQs of electron shells as it leads you on a whiz-bang tour of the periodic table. We carefully shrinkwrapped the contents into a highly charged fusion of facts and fun. Please use caution when opening.
