  3. A nuclear reaction is represented by the following equation. This reaction is an example of A. fission. B. fusion. C. natural transmutation. D. artificial (induced) transmutation. (Total 1 mark)

  4. The process by which a heavy nucleus splits into two lighter nuclei is known as A. fission. B. fusion. C. radioactive decay. D. artificial (induced) transmutation. (Total 1 mark)

  5. Atoms are lighter than the nucleons which they are built from the mass defect, δ mass from n and p  energy released as nucleus is made Tsokos p.387qn1

  6. Binding energy of lithium mass of a lithium-7 nucleus = 7.01600u mp = 1.00728u mn = 1.00866u • calculate the mass defect of lithium: (i) in u (ii) in kg • calculate the binding energy of lithium (i) in J (ii) in MeV • calculate the binding energy per nucleon in MeV

  7. Binding energy per nucleon

  8. Nuclear fusion

  9. Nuclear fission The sun

  10. Fission and fusion How does the curve of binding energy per nucleon explain why fission of heavy elements releases energy, while fusion of light elements releases energy?

  11. Binding energy binding energy of the nucleus is the energy needed to separate the nucleons

  12. mass in MeVc-2 using we can use units for mass of energy/speed of light 1 GeVc-2 = 1.783×10−27 kg How many MeVc-2 is 1u? Calculate the mass defect of lithium-7 in MeVc-2 and use this to calculate the energy released per nucleon.
