More info:
Promethium is extremely rare in the earth's crust and produced artificially in laboratories by nuclear reactions on Uranium. Because of its rare occurrence, the chemistry of Promethium is not that well explored. This, however, does not make Promethium a boring element! Spectra of certain stars in the Andromeda galaxy show signatures of Promethium and the radioactive decay of Promethium has been utilized in designing atomic batteries!
