What are three compounds containing promethium?
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.
What phase changes can happen to promethium?
Promethium can be melted and boiled.
How does promethium smell like?
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.
Can promethium be used on edible plants?
It is impossible, promethium is highly radioactive.
What is the chemical symbol fo promethium?
The chemical symbol of promethium is Pr.
What two 'light' elements have no stable nonradioactive isotopes?
The two elements are elements 43, Tc, technetium, and 61, Pm, promethium. Technetium has a few "nearly stable" isotopes with half-lives of over a million years. Promethium's longest lived isotope has a half-life of about 20 years.
What substances are in promethium bromide?
Promethium bromide contain promethium and bromine.
How much is promethium per pound?
Promethium is a highly radioactive element primarily created in the laboratory, though several of it's isotopes can exist in nature (it's longest-lived isotope has a half-life of only 17 years). It is estimated that in nature, no more than 560 grams (a little over a pound) of Promethium exists in the entire crust of the earth.
Is Promethium magetic?
Yes, Promethium is a radioactive element that is paramagnetic, meaning it is weakly attracted to magnetic fields.
