WebPromethium is a chemical element or rare earth metal in the periodic table with the symbol Pm and atomic number 61. It is a radioactive lanthanide or f-block element that is extremely rare in Earth’s crust. All the isotopes of promethium are radioactive and found naturally by the spontaneous fission of uranium -238. A promethium atom has 61 electrons, arranged in the configuration [Xe] 4f 6s . The seven 4f and 6s electrons are valence. In forming compounds, the atom loses its two outermost electrons and one of the 4f-electrons, which belongs to an open subshell. The element's atomic radius is the second largest among all the lanthanides but is only big slightly greater than those of the neighboring elements.
