Radium, like barium, is a highly reactive metal and always exhibits its group oxidation state of +2. It forms the colorless Ra cation in aqueous solution, which is highly basic and does not form complexes readily. Most radium compounds are therefore simple ionic compounds, though participation from the 6s and 6p electrons (in addition to the valence 7s electrons) is expected due to relativistic effects and would enhance the covalent character of radium compounds such as RaF2 and RaAt2. … WebRadium is a chemical element with the symbol Ra.
