Match the scientist with the contribution they made to the atom or the periodic table: 1. Dimitri Mendeleev a. I discovered the electron using a cathode tube & my atom model is called the “plum pudding” model. 2. John Dalton b. I worked with organizing the periodic table using atomic numbers. 3. Democritus & Aristotle c. My atomic model helped describe the orbits of electrons, has been called the planetary model & is still used today. 4. J.J. Thomson d. I was the first to call the atom as “atomos” 5. Henry Moseley e. I believed that atoms could not be broken down 6. Niels Bohr f. I used the Gold Foil Experiment to discover a + charged nucleus. They call my model the “planetary system” 7. Ernest Rutherford g. I organized the 1st periodic table using atomic masses.
