Promethium has similar chemical properties as cerium and other lanthanoids.
Promethium is a radioactive, silvery metallic element that is rare in its pure form. It may appear similar to other metallic elements but is distinguished by its radioactivity and glowing properties. In practical applications, promethium is usually in the form of a phosphor or a powder used in luminous paint or in radioactive power sources.
Promethium has similar chemical properties as cerium; the oxidation state is 3+.
Promethium bromide contain promethium and bromine.
Promethium is not flammable.
Yes, Promethium is a radioactive element that is paramagnetic, meaning it is weakly attracted to magnetic fields.
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.
Promethium is not soluble in water.
Promethium is typically a solid at room temperature, specifically a metal.
