Marie Curie

Lishia, Christian, Carleigh


Discovery

Discovery

  • Found Radium and Polonium

  • Found Radioactivity


Experiment

Experiment

  • Marie Curie with her husband examined activity in radium and pitchblende

  • It supported her theory that pitchblende is more radioactive than uranium

  • Particles of unknown radiation were found in pitchblende


Analyzing

Analyzing

  • Pitchblende-form of the mineral uraninite

  • Uraninite- mixture of radium and uranium

  • Marie used the process of elimination to find out which combination of elements is in uraninite, radium and polonium


Conclusion

Conclusion

  • In 1898, the Curie’s discovered radioactive elements radium and polonium

  • Radium was isolated by electrolysis or a solution of pure radium, chloride, employing a mercury cathode
