  • Discovered idea of radioactive half-life
  • Credited with the first splitting of the atom in 1917
  • Earned Nobel Prize in Chemistry for his theory of atomic structure in 1908
  • Focused on nuclear reactions in his late career

Major Contributions

  • Came up with Rutherford model of atom; said that their charge was in a small nucleus
  • Most famous experiment happened after the Nobel Prize
  • Experiment with Hans Geiger and Ernest Marsten called the Geiger-Marsten experiment, also called the Gold Foil Experiment
  • It showed the nuclear nature of atoms by deflecting alpha particles passing through a thin gold foil


BIG IDEA: Came up with the nuclear structure of the atom
