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
