    Democritus (460 BC)
    Democritus theorized that if you keep cutting and object in half, you will eventually get t a point where you cannot cut it in half anymore. "GaggleTube Video - Models of the Atom Timeline." GaggleTube Video - Models of the Atom Timeline. N.p., n.d. Web. 26 Feb. 2014.

    Aristotle(400s B.C.)

    Aristotle did not believe in atoms and said that things were amde up small amounts of water,earth,air,fire, or ether. Allain, Rhett. "GaggleTube Video - Models of the Atom Timeline." GaggleTube Video - Models of the Atom Timeline. Science Blogs, 4 Sept. 2009. Web. 26 Feb. 2014.

  • Dalton

    Dalton
    Dalton discovered that all matter was made of particles by doing experiments that showed that matter was made up of tiny particels. Allain, Rhett.

  • Thomson

    Thomson
    He used a cathode ray tube and a power source to shoot a ray through the tube, and then used magnets to see if the ray had an electrical charge and discovered that atoms contained smaller particles.

  • Rutherford

    Rutherford
    He discovered the nucleus of atoms by doing an experiment that used particles to hit a thin piece of foil and saw that some of the particels were deflected by the foil.

  • Bohr

    Bohr
    Bohr used a mathematical equation and Rutherford's experiment and concluded that electrons orbited the nucleus like planets.
