On this page I'll provide comprehensive data for Cerium. I hope you profit from it.
Cerium Overview
Name Origin
Named after the asteroid, Ceres, discovered two years before the element.
Symbol
Ce (Cerium)Description
Malleable, ductile, iron-gray metal.
Discovery
Discovered By: W. von Hisinger, J. Berzelius, M. Klaproth
Year: 1803
