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.

Promethium is a radioactive chemical element, atomic number 61. Promethium was identified and prepared for the first time in 1945, at Oak Ridge, USA by Jacob A. Marinsky, Lawrence E. Glendenin, Charles D.Coryell, Harold G. Richter. Pm exist also as a natural element in uranium ores but only in ultra traces amounts impossible to be exploited. Promethium is obtained today by separation from fission products of uranium-235. Promethium, with a Pauling electronegativity of approx. 1,13 is a reactive metal.

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.
