  1. The fuel used in most high-yield thermonuclear weapons is solid lithium 6 deuteride. These weapons, commonly known as "hydrogen bombs" or "H-bombs", use the energy released when a nucleus of light lithium (63Li, m = 6.015121 u) and heavy hydrogen, also known as deuterium (21H, m = 2.0140 u), fuse to form two nuclei of ordinary helium (42He, m = 4.00260 u).
    1. Write this nuclear reaction out in symbolic form.
    2. What is the mass defect when one molecule of lithium 6 deuteride is transformed into two atoms of helium? State your answer in…
      1. atomic mass units
      2. megaelectronvolts
      3. joules
      4. kilograms
  2. Calculate the binding energy (in MeV) liberated in each of the following nuclear reactions.
    1. Alpha decay

      21084Po → 20682Pb + 42He

    2. Beta decay, isolated

      10n → 11H + 0−1e + 00ν̅

    3. Beta decay, nucleic

      3215P → 3216S + 0−1e + 00ν̅

    4. Neutron capture

      10n + 10345Rh → 10445Rh

    5. Fusion

      21H + 21H → 31H + 11H

    6. Fission

      10n + 23592U → 14156Ba + 9236Kr + 310n
