Marie Curie's second Nobel PrizeIn 1911, at Stockholm, Sweden, Marie Curie became the first person to be awarded a second Nobel prize. She had isolated radium by electrolyzing molten radium chloride. At the negative electrode the radium formed an amalgam with mercury. Heating the amalgam in a silica tube filled with nitrogen at low pressure boiled away the mercury, leaving pure white deposits of radium. This second prize was for her individual achievements in Chemistry, whereas her first prize (1903) was a collaborative effort with her husband, Pierre Curie, and Henri Becquerel in Physics for her contributions in the discovery of radium and polonium. |
