Marie+Curie(GD)

Marie Curie She helped to discover Polonium and Radium.To do this she and her husband took Pitchblend, which contained the radioactive element Uranium by the ton and carefully isolated the radioactive components over several years. What they found was that there were more than one radioactive element in it because they found an element that was far more radioactive than the element uranium. She got a Nobel in Physics for radioactivity. She got a Nobel in chemistry for discovering two new elements. After completing this experiment, Curie discovered that all atoms are not alike and that the theory that all atoms are structured identically should be abandoned (Dr. Reich’s Power Point)
