Quizplus · Accepted Answer

The strong nuclear force is the powerful force that holds the protons and neutrons together in the nucleus of an atom. It overcomes the repulsive force between the positively charged protons, and is responsible for the stability of the nucleus. A) Binding energy is the energy required to break apart a nucleus, which is related to the strength of the strong nuclear force. C) Fusion and D) Fission are processes that involve changes in the nucleus but do not directly relate to the force holding it together.
