Promethium is an artificial chemical element discovered in burned uranium fuels as a fission product.
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.
Promethium 145 has a half life of 17.7 years. Promethium 146 has a half life of 5.53 years. Promethium 147 has a half life of o.22 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.
The chemical symbol of promethium - Pm - is derived from this name.
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.
Promethium is not soluble in water.
Promethium is typically a solid at room temperature, specifically a metal.
Promethium, a radioactive element, does not have a distinct smell. It is typically stored in a sealed container due to its radioactivity, so people do not come into direct contact with it and experience its smell.
