Promethium is a natural chemical element. But because exist in nature only in ultratraces it is artificially prepared.
Promethium does not occur naturally on Earth and is primarily synthetic. At room temperature, promethium is expected to be a solid metal.
Technetium (43), Promethium (61), and all the transuranic elements are synthetic.
Promethium (Pm) is the only synthetic element in the lanthanide series. It is not found naturally on Earth and is typically produced in nuclear reactors.
Technetium, Tc, and promethium, Pm
Promethium bromide contain promethium and bromine.
Yes, Promethium is a radioactive element that is paramagnetic, meaning it is weakly attracted to magnetic fields.
Promethium is not flammable.
Promethium salts, oxides, and halides are common compounds of promethium. Promethium oxide (Pm2O3) and promethium chloride (PmCl3) are among the compounds that can be formed with promethium.
Yes. Promethium is a solid.
Promethium is not flammable.
Promethium is a metal.
Promethium has 61 protons.
