Description

Cerium is a rare earth metal and the most abundant member of the lanthanide series discovered by Jons J. Berzelius and W. von Hisinger in 1803 in Sweden. Berzelius and Hisinger discovered the new element in a rare reddish-brown mineral now known as cerite, a cerium–lanthanide silicate. Although they could not isolate the pure metal, they found that cerium had two oxidation states: trivalent state (Ce3+, cerous, usually orangered) and the tetravalent state (Ce4+, ceric, usually colorless). Cerium is the only material known to have a solid-state critical point.
