What are the physical and chemical properties of promethium?
After the Pauling electronegativity (1,13) 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.
What is the physical state of promethium at room temperature?
The radioactive metal, Promethium, is a solid at room temperature and standard pressure. It becomes a liquid at 1040ºC and a gas or vapor at 3000ºC.
Is promethium representative or transition element?
Promethium is a transition element. It is the only element in the lanthanide series that is radioactive and does not occur naturally on Earth. Its atomic number is 61, and it is commonly used in nuclear batteries and research applications.
What element was discovered first hydrogen or promethium?
Hydrogen was discovered first in 1766, while promethium was discovered much later in 1945.
What came first hydrogen or promethium?
Hydrogen as the atomic number 1 and promethium has the atomic number 61.
What is similar to promethium?
Promethium has similar chemical properties as cerium and other lanthanoids.
Is promethium a conductor of heat?
Yes, promethium is a conductor of heat. It has good thermal conductivity properties, which means it can transfer heat efficiently.
What is promethiums chemical properties?
Promethium has similar chemical properties as cerium; the oxidation state is 3+.
How is promethium different from the other lanthanides?
Promethium is the only lanthanide that is radioactive and does not have stable isotopes. It is also challenging to study due to its radioactivity. Additionally, promethium has unique chemical properties compared to other lanthanides.

What does the promethium look like?
Promethium is a radioactive, silvery metallic element that is rare in its pure form. It may appear similar to other metallic elements but is distinguished by its radioactivity and glowing properties. In practical applications, promethium is usually in the form of a phosphor or a powder used in luminous paint or in radioactive power sources.
What substances are in promethium bromide?
Promethium bromide contain promethium and bromine.
Is promethium flamable?
Promethium is not flammable.
Is Promethium magetic?
Yes, Promethium is a radioactive element that is paramagnetic, meaning it is weakly attracted to magnetic fields.
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.
Is promethium a solid?
Yes. Promethium is a solid.
Is promethium a flamable element?
