'''Cerium''' ''(SER-ee-em)'' was discovered by Jöns Jacob Berzelius and Wilhelm von Hisinger, Swedish chemists, and also independently by the German chemist Martin Heinrich Klaproth, in 1803. It is one of the [[rare earth elements]]. Cerium is considered to be moderately toxic.<ref>http://education.jlab.org/itselemental/ele058.html</ref>
Cerium is a reactive, soft, gray, lustrous [[metal]] that is malleable and [[ductile]].<ref>http://www.chemicool.com/elements/cerium.html</ref> It is also somewhat flammable.<ref>http://education.jlab.org/itselemental/ele058.html</ref>
==Uses==
Cerium is used for a number of things, including carbon arc lights (used in the movie industry, and other places),<ref>http://www.chemicool.com/elements/cerium.html</ref> the walls of self-cleaning ovens, and even lighter flints.<ref>http://education.jlab.org/itselemental/ele058.html</ref> Cerium oxide and other Cerium compounds are also used for glass treatment.
