PHYSICS (SECONDARY) ESSENTIAL UNIT 9 (E09) (Atomic and Nuclear Physics) (June 2011) Unit Statement: In essential unit nine, the student will also learn that certain elements radiate particles and turn into other elements. The student will also learn that nuclear fission and nuclear fusion reactions release huge amounts of energy. Essential Outcomes: (must be assessed) 1. The Student Will describe the significance of Rutherford’s Gold Foil experiment on the discovery of the atomic nucleus. 2. TSW explain what determines the radii of the electron orbits in the Bohr model of the atom and its correlation to integral wavelengths in quantum mechanics. 3. TSW distinguish among the three types of radiation given off by radioactive elements. 4. TSW explain the factors that determine the penetrating power of radiation. 5. TSW explain how the isotopes of an element are similar and different. 6. TSW describe the role of the role of neutrons in atomic nuclei. 7. TSW describe some uses of radioactive isotopes. 8. TSW describe which elements have been produced through transmutation. 9. TSW describe the conditions necessary to sustain a nuclear chain reaction. 10. TSW compare the total mass of the products of fusion to the mass of nuclei that fused. SUGGESTED RESOURCES & RUBRIC FOUND ON FOLLOWING PAGES…………………….
