    Aristotle BC
    He didn't believe the atomic theory however he believed in earth, wind, and fire. His method was memeory. "Aristotle." Aristotle. N.p., n.d. Web. 14 Mar. 2014.

    Democritus BC

    Democritus BC
    He discovered all atoms are indestructible , atoms are solid but invisible , atoms are homogenous and atoms differ in size, mass, position, and arrangement . He used Leucippus method to make his discoveryof the atoms . He hypothisized , that atoms cannot be destroyed differ in size, shape, temp. are always moving and are invisible . "Democritus." Democritus. N.p., n.d. Web. 14 Mar. 2014

  • Dalton

    Dalton
    formulated an atomic theories of matter with postulates .
    1. elements are composed of small particles called atoms .
    2. all elements of a given element are identical.
    3.aroms are neither created nor destoyed in Chemical reactants. "Molecules." Molecules. N.p., n.d. Web. 14 Mar. 2014.
    4. compounds always contain the same proportron of elements.
    the constructed a table of the relative atomic weights of a handful of elements the started using symbols to represent the atoms of diffferent elemts.

  • Thomson

    Thomson
    He discovered the Plumpudding model of the divisible atom. His method was was the properties of cathode rays. he concluded the rays were composed of very light, negatively charged particles,"Thomas Nagel." Thomas Nagel. N.p., n.d. Web. 14 Mar. 2014.

    Ruthford
    He dsicovered the nucleus and added elements. His method was the gold foil experiment. "Rutherford - Atomic Theory." Rutherford - Atomic Theory. N.p., n.d. Web. 14 Mar. 2014.

  • Bohr

    Bohr
    He developed the quantized orbit model of the atom, electrons can only reside in certain energy levels."Niels Bohr." Niels Bohr. N.p., n.d. Web. 14 Mar. 2014.

  • Heisenberg and Schrodinger

    Heisenberg and Schrodinger
    They developed the quantum mechanical model of the atom. They used the wave function to figure this out. "Erwin Schrödinger." Erwin Schrödinger. N.p., n.d. Web. 14 Mar. 2014.
