Multiple choice. **Instructions:** Identify and underline the correct answer. (0.5 points each, 6 points total) 1. Bohr's atomic structure theory is about: - A. Electron's arrangement in atoms as orbits - B. The nucleus. - C. The proton and its positive charge. - D. The electron and its negative charge. 2. Ernest Rutherford discovered: - A. The atomic nucleus and the proton with its positive charge - B. The atoms in a specific element are different from those of another element - C. The electron and its negative charge - D. All of the above 3. One of Erwin Schrödinger's greatest contributions to the atomic model was: - A. The more precisely the position is determined, the less precisely the momentum is known in that instant, and vice versa - B. He warned that a nuclear decay chain could produce a devastating bomb. - C. There are regions in the atom with high probabilities where an electron can be found - D. He discovered the atomic nucleus and the proton which has a positive charge. 4. The first philosopher to propose the existence of the atom was: - A. Democritus - B. Aristotle - C. Rutherford - D. Thomson 5. Scientist who identified the electron and its negative charge: - A. Thomson. - B. Lavoisier. - C. Rutherford. - D. Bohr. 6. Dalton's atomic theory establishes that: - A. Matter is made out of atoms. - B. Atoms are indivisible and indestructible. - C. Different atoms combine to form compounds. - D. All of the above. 7. The three fundamental subatomic particles are: - A. Nucleus, protons, and neutrons - B. Electron, proton, and neutron - C. Nucleus, atom, and proton - D. All of the above. 8. What is true about atoms is: - A. They are electrically neutral. - B. Protons and neutrons are located at the nucleus of the atom. - C. The electrons of an atom move around the nucleus. - D. All of the above. 9. The subatomic particle with a positive electric charge is: - A. Proton - B. Neutron - C. Electron. - D. All of the above. 10. They are negatively charged particles that are part of all forms of matter: - A. Protons - B. Electrons - C. Neutrons - D. Nucleus 11. The subatomic particle which has NO electric charge is: - A. Proton. - B. Neutron. - C. Electron. - D. All of the above. 12. Scientist who established the uncertainty principle: - A. Rutherford - B. Thomson - C. Aristotle - D. Heisenberg ## **Section II. Short answers.** **1. Draw and label the structure of the atom, including its subatomic particles. (3 points)** The image shows a diagram of an atom. In the center is the nucleus, containing protons and neutrons. Surrounding the nucleus are multiple rings of electrons. **2. Distinguish between the ideas of Democritus and Joseph John Thomson. (4 points).** Democritus proposed the existence of atoms, called "atomos" in that time meaning indivisible. Thomson identified the electron.
