The Center of the Central Science

Dmitri Mendeleev’s organization of known elements according to their properties was the catalyst chemistry needed to spur an explosion of discovery of new elements.  We’re joining the scientific community in celebrating the International Year of the Periodic Table and recognizing the discovery of the known elements as well as new elements just over the horizon.

Go on an element hunt and collect all the magnetic elements pieces to complete your own periodic table poster. See below to find out how.

Discover facts you may not have known about the elements in the periodic table on our Elements Page.
