Rare-earth element

Despite their name, rare-earth elements are relatively plentiful in Earth''s crust, with cerium being the 25th most abundant element at 68 parts per million, more abundant than copper. All isotopes of promethium are radioactive, and it does not occur naturally in the earth''s crust; however, a trace amount is generated by decay of uranium 238.
