Do you have a textual description of promethium?
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.
