-Scientist name (J.J. Thomson, Ernest Rutherford, Niels Bohr, John Dalton, James Chadwick, Democritus)
-Time period the scientist studied the atom
-the scientist's major contribution to the understanding of the atom
-A picture of which would best represent his findings (the model he came up with, his famous experiment that let him to the discovery)
