What is Promethium?
Promethium is an extremely radioactive chemical element classified among the rare earth metals on the periodic table. The element does not seem to appear naturally on earth, although it has been successfully created through artificial means. Promethium is also observed in the spectra of some stars, probably because of the nuclear reactions which occur in stars. Average consumers rarely interact with promethium, given its extreme rarity and highly specialized applications. The appearance of promethium is a topic of discussion, since pure natural promethium has not been identified. It seems to have two allotropic forms, meaning that the structure of the element can vary in at least two ways when it is purified. In addition to being radioactive itself, promethium also produces a number of radioactive isotopes, some of which are very useful in various industries. On the periodic table of elements, promethium can be found under the symbol Pm, and it has an atomic number of 61, which places
