    Aristotle (340 B.C.)

    He Did Not Believe in Atoms and taught about how everytihng was made of Water,Fire,Earth,and Air.

    Democritus (400BC)

    He said that everything was made of atoms that are unbreakable, solid, and invisible. He called them "ATOMOS." "GaggleTube Video - The History of Atomic Chemistry: Crash Course Chemistry #37."

  • Dalton

    Dalton

    He said the same as Democritus but he experimented with chemicals and his atom was also similar to Democritus "GaggleTube Video - The History of Atomic Chemistry: Crash Course Chemistry #37."

  • Thomson

    Thomson

    He discovered the mass and electrons but called them "CORPUSCLES." He measured how much heat the cathode rays generated by how much they could be bent by magnets.

    Bohr

    He modified Rutherfords Atom
    He also studied with Rutherford
    Made the planetary model "Bohr Atomic Model." Bohr Atomic Model. N.p., n.d. Web. 24 Feb. 2014.
  • Rutherford

    Rutherford

    He discovered the nucleus and most of the atom is empty discovered protons space. He used a thin sheet of gold foil to experiment.
