Atom

Timeline of the Atom

  • John Dalton

    John Dalton preformed the first expiriment testing the atom theory.
  • J.J. Thompson

    Discovered the electron and construted a model for the atom
  • Max Planck

    Figured out that if you vibrate atoms strong enough (such as when you heat it up) you can measure the objects in units.
  • Ernest Rutherford

    Shot Alpha Rays at Atoms to see the effect.
  • Niels Bohr

    Created theory stating that electrons did not spiral in ward, but simply jumped between possible planes
  • Ernest Rutherford

    Constructed an atom model that was close to an acurate representation of one
  • Wolfgang Pauli

    Guessed that electrons spin as they orbit around the nucleus
  • Louis de Broglie

    Predicted that atom particals can act as waves. (He was later proven correct)
  • Paul Dirac

    Constructed equations that posed a theory for Anti-Matter.
  • James Chadwick

    Discovered the Neutron
  • Werner Heisenberg

    Found that charged photons bounce light beams back and forth between them.
  • Anti-Matter

    Physicsts discovered the "anti-proton" and the "anti-neutron" thu proving antimatter true
  • Murray Gell-Mann and Yuval Ne'man

    Created the Eightfold method of classification
