cerium
n 1: a ductile grey metallic element of the lanthanide series;
used in lighter flints; the most abundant of the rare-earth
group [synonym: {cerium}, {Ce}, {atomic number 58}]

Cerium \Ce"ri*um\, n. [Named by Berzelius in 1803 from the
asteroid Ceres, then just discovered (1801).] (Chem.)
A rare metallic element, occurring in the minerals cerite,
allanite, monazite, etc. Symbol Ce. Atomic weight 141.5. It
resembles iron in color and luster, but is soft, and both
malleable and ductile. It tarnishes readily in the air.
