Radium (Ra) Atomic Number = 88 Mass = 226.0 g mol -1 Electron Configuration = [Rn]7s 2 Density = 5.5 g cm-3. Radium was first discovered in 1898 by Marie Sklodowska-Curie, and her husband, Pierre Curie, in a pitchblende uranium ore in North Bohemia in the Czech Republic; however, it was not isolated as a pure metal until 1902.
