Physics Unit 5 Nuclear Energy 3.0 / 5 based on 4 ratings ? PhysicsNuclear physicsA2/A-levelAQA Created by: Nicola HansonCreated on: 12-04-13 18:27 What is the definition of binding energy? Work done to completely separate a nucleus 1 of 17 What is the definition of binding energy per nucleon? Work done per nucleon to remove all nucleons from a nucleus 2 of 17 What is the measure of the stability of a nucleus? Binding energy per nucleon 3 of 17 For the notation of an element, what does A mean? Number of protons and nucleons in a nucleus 4 of 17 For the notation of an element, what does Z mean? Number of protons in a nucleus 5 of 17 What is the equivalent energy of an atomic mass unit? 931MeV 6 of 17 What is the definition of nuclear fission? A large unstable nucleus splits into two smaller nuclei 7 of 17 What is the definition of nuclear fusion? Two nuclei form a more stable nucleus 8 of 17 What is the element with the most stable nucleus? Iron 9 of 17 What elements are used for nuclear fission? Uranium and plutonium 10 of 17 Which process occurs when you bombard a nucleus with neutrons? Fission 11 of 17 What are the products of nuclear fission? Two nuclei and approx two neutrons 12 of 17 Why does fission produce energy? Positive nuclei fly apart, kinetic energy is equal to mass defect 13 of 17 How do you determine the energy released from fusion? Increase in binding energy 14 of 17 What force is overcome for fusion to occur? Electromagnetic repulsion 15 of 17 What force causes nuclei to fuse? Strong force 16 of 17 What is the definition of mass defect? Difference between mass of separated nucleons and mass of a nucleus 17 of 17
