  • Joseph John Thomson

    Joseph John Thomson
    Thompson came up with the "plum pudding model" for the atom. He was the first scientist to propose that the atom was not the smallest particle but in fact contained small negative particles called electrons. He proposed that these electrons sat in a positive jelly like plums in a plum pudding.
  • Ernest Rutherford

    Ernest Rutherford
    Ernest Rutherford fired alpha particles (tiny positively charged particles) at a thin sheet of gold foil and found out that although most alpha particles went straight through the sheet, some were deflected or even reflected back towards their source.
  • Niels Bohr

    Niels Bohr
    Neils Bohr used evidence from atomic absorption and emission spectra to suggest a more detailed structure of the atom.
  • Louis-Victor de Broglie

    Louis-Victor de Broglie
    In 1924, Louis de Broglie suggested that electrons can actually behave like particles and waves - "wave-particle duality".
