3 Accomplishments Nobel Prize for Physics 1906 Royal Medal 1894 Hughes Medal in 1902 Elliot Cresson Medal in 1910 Copley Medal in 1914 Franklin Medal in 1922

4 The Experiments that led to the discoveries. He discovered Electrons, Isotopes and created the mass of a spectrometer. Discovered the natural radioactivity of potassium in Demonstrated Hydrogen has one electron per atom.

5 Experimental Data Does your scientist’s model of the atom fit with experimental data? No, because no one believed that atoms could be broken down. Everyone thought that the atom was the ultimate particle.

6 The Atomic Structure He proved that atoms were divisible and showed that atoms were made up of electrons, protons, and neutrons. He discovered a method for separating different kinds of atoms and molecules by the use of negative rays.
