Q1:

Which of the following correctly describes the process of induced nuclear fission?

  • AThe nucleus of an atom of a fissionable substance is struck by a neutron, causing the nucleus to split into two smaller fragment nuclei and release several neutrons.
  • BThe nucleus of an atom of a fissionable substance is struck by a neutron, which is absorbed. The nucleus then becomes unstable and decays via beta decay.
  • CThe nucleus of an atom of a fissionable substance is struck by a proton, causing the nucleus to split into two smaller fragment nuclei and release several protons.
  • DThe nucleus of an atom of a fissionable substance is struck by a neutron, causing the nucleus to split into at least three smaller fragment nuclei.
  • EThe nucleus of an atom of a fissionable substance is struck by an electron, causing the nucleus to split into two smaller fragment nuclei and release several electrons.

Q2:

Which of the following correctly describes the process of spontaneous nuclear fission?

  • AThe nucleus of an atom splits without being struck by a neutron, resulting in two smaller nuclei and two or three high-speed neutrons.
  • BTwo atomic nuclei collide and combine to form a single larger nucleus.
  • CThe nucleus of an atom of a fissionable substance is struck by a neutron, causing the nucleus to split into two smaller fragment nuclei and release several neutrons.
  • DThe nucleus of an atom splits without being struck by a neutron, resulting in at least three smaller nuclei and two or three high-speed protons.
  • EThe nucleus of an atom of a fissionable substance is struck by a proton, causing the nucleus to split into two smaller fragment nuclei and release several protons.

Q3:

Which two of the following are used as fuel in nuclear fission reactors?

  1. Iridium
  2. Lead
  3. Uranium
  4. Polonium
  5. Plutonium
  • Ac and e
  • Bc and d
  • Ca and b
  • Dd and e
  • Eb and c
