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 can be melted and boiled.
The half-life of promethium-145 is approximately 17.7 years. Promethium-147 has a half-life of about 2.62 years.
Promethium does not occur naturally on earth, but as a by-product of uranium fission. It is very radioactive and its salts have a pinkish or reddish color. Promethium colors its surrounding air with a pale blue-green light.
It is impossible, promethium is highly radioactive.
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.
