Examples are: PmF3, Pm(OH)3, Pm2O3.
Promethium is an element and does not have a charge. As it has only be found in trace quantities, its chemistry has not been fully investigated. It has been anticipated that the likely charge when it forms compounds would be +3.
uranis has the most compounds
Promethium from Prometheus, who stoled the fire from Zeus.
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 itself does not have an odor as it is a radioactive metallic chemical element. However, compounds containing promethium may have their own distinct odors depending on their chemical nature.
Promethium is a radioactive element and does not have a characteristic odor on its own. Any odor associated with promethium would likely be from compounds or substances it is combined with in a laboratory setting.
Promethium itself does not have a distinct odor as it is a rare earth metal. However, some of its compounds may have a metallic smell when they react with other chemicals.

After the Pauling electronegativity promethium is a reactive metal but the chemistry of Pm is only superficially known.The valence of ions in solution is +3. Promethium compounds known: halides, oxides, nitrates, sulfates, hydroxides etc.

The melting point of promethium is 1 024 0C.
Water, ethanol, and octane (a constituent of most gasoline).
Every single organic thing contains carbon.
they are called inorganic compounds
Carbon containing compounds found in living things are called organic compounds. Examples of organic compounds are carbohydrates, proteins, lipids and nucleotides.
Compounds containing carbon are referred to as organic compounds
