Cerium is a chemical element, with the Ce symbol and atomic number 58. It is part of the lanthanide family.
Cerium was identified in 1803 by Martin Heinrich Klaproth and almost simultaneously by Jöns Jacob Berzelius and Wilhelm Hisinger. Its name refers to the dwarf planet "Ceres" discovered in January 18017. In 1825, it was obtained by Carl Gustav Mosander for the first time in a reasonably pure state.
