Lesson: Nuclear Fission

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?
