Mineral Species containing Cerium (Ce)

Element Properties, Isotopic Compositions for Cerium

**Cerium (Ce) Element Properties**
Atomic Mass	140.115
Atomic Number	58
Name Origins	Named after the asteroid Ceres, discovered in 1801
Year Discovered	1803
Discovery Credits	Discovered by J. J. Berzelius and W. Hisinger at Vestmanland, Sweden. First isolated by W. F. Hillebrand and T. H. Norton in 1875 at Washington, DC, USA
Remarks	Reactive, gray metal, most abundant of the (Rare Earth) lanthanide metals. Tarnishes in air, burns when heated, reacts rapidly with water, dissolved in acids. Used in glass, gas mantles, ceramics, and alloys. Misch alloy ( predominantly Ce) is used for lighter "flints". Diagnostic tests: There are no simple diagnostic tests to identify cerium. Infusible cerium minerals glow with exaggerated incandescence in the flame test (along with Sr, Mg, Zr, Zn, Ca - the "lime light effect").
