Natural promethium is exceedingly scarce, it is typically synthesized in a nuclear reactor by bombarding uranium-235 (enriched uranium) with thermal neutrons to produce promethium-147, which has a halflife of 2.6234 years.
When promethium is needed it is usually synthesized, separated, and prepared in the buyer's desired chemical form just for that order. It is not kept in stock because it would likely decay significantly between manufacture and shipment. Only licenced industrial and research facilities are allowed to submit orders for promethium, not individuals.
Currently, Russia is the only country producing promethium-147 on a relatively large scale.
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.
Promethium is not soluble in water.
Yes. Promethium is a solid.
Promethium is not flammable.
Promethium is a metal.
Promethium has 61 protons.
Promethium is typically a solid at room temperature, specifically a metal.
Yes, promethium is flammable. It can ignite spontaneously in air and react with oxygen to produce heat and flames. Special precautions are necessary when handling promethium to prevent accidental fires.
Promethium is a rare artificial element.
