  • John Dalton

    Proposed the atomic theory.
  • Period: to

    J. Plucker, James Clark Maxwell, Sir Williams Crookes, Henri Becquerel

    During this time the Gas chamber tube was made, Figured out that electric and magnets filled void, learend about the cathrode rays, which all together creatingthe cathrode tube that help lead to the next atomic model.
  • J.J. Thomson

    J.J. Thomson
    Proposed that the atom has electrons.
  • Hanataro Nagaoka

    Proposed that the electrons were set like saturn rings.
  • Rutheford

    Rutheford
    Proposed that the atom's electon is wizzing aroundthe nucleus. He figued this out by using the cathrode tube studying it indirectly.
  • Neils Bohr

    Neils Bohr
    discovered that electrons has orbitals that explained that they are in energy levels.
  • Period: to

    Broglie, Schrodinger, and other scientists

    studied and figured out the electron cloud. Also learned about chain reactions and leading to wavelengths. leadingto more knowledge and theories.
