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.
It is impossible, promethium is highly radioactive.
The chemical symbol of promethium is Pr.
Promethium is a rare earth metal that is usually found in a dull gray color. However, when freshly cut or newly isolated, it can have a shiny appearance due to its metallic luster.
Promethium bromide contain promethium and bromine.
Yes, Promethium is a radioactive element that is paramagnetic, meaning it is weakly attracted to magnetic fields.
