    Democritus 450 BC
    Democritus was one of the first people to discover the atom.
    His experiment envolved a slice of bread. Then he sliced the bread into four peices and discovered atomos (atomos = uncuttale). Democritus's visual of a atom with salt would have spikes all over it.

    dalton
    Dalton was one of the first people to make a model of a atom.
    He also proved that they were made of particals. Dalton conducted multiple experiments Until he found that atoms were made a many small particals. Dalton also thought they were made up of little balls arranged in different Dalton Atomic Model - Google Search." Dalton Atomic Model - Google Search. N.p., n.d. Web. 05 Mar. 2014.
  • Thomson

    Thomson
    Thomson discovered that atoms have electrons and that these electrons are smaller than the rest of the atom. He found this information conducting the cathode ray tube experiment. After the experiment he created the Plum Pudding model that showed the way he thought the atom looked, which many refer to as a blue muffin.

    RutherFord
    He founded that the positive partical was concentrated in the center. RutherFord also conducted the Gold foil experiment. His visual of the atom was shown in the nuclear model.

  • Bohr

    Bohr
    Bohr's theroy of what the atom looked like was that the electrons spun around the nuclues. Bohr's visual of the atom was that it was identical to the solar system.

  • Heisenburg and Schrodinger

    Heisenburg and Schrodinger
    These men showed that electrons were not orbiting around the nueclus in a solar system like path but they that they went around the nueclus in a very uneven path. They showed this in the Quantum Mechincal Model.

  • Aristotle 350 BC

    Aristotle 350 BC
    Aristotle stated that atoms were not real but matter was made of Earth, Wind, Water, and Fire. Since Aristotle was much more famous than any other scientist at that time his theory was accepted.
