A radioactive lanthanide element with the symbol Pm and atomic number 61. It is one of the rarest and most expensive elements in the Periodic Table, with only about 500–600 grams naturally occurring in Earth’s crust at any given time. It is produced by the decay of uranium or europium, and has one stable isotope (147 Pm) with applications in luminous paint, atomic batteries and thickness-measurement devices.
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.
Promethium is a metal.
Yes. Promethium is a solid.
Promethium is not flammable.
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.
