About cerium: Cerium is one of the members of the group of elements know as the rare earths. There are sixteen elements in this group. The word "earth" was used to describe the oxide of metals. The word "rare" was applied to these sixteen elements because it was believed that their metal oxides were not present in any great quantity in the Earth's crust. In fact, for most of the elements in this group, this is not the case. Their metal oxides are quite abundant, although they often occur mixed with other compounds.
