Question

Quizplus · Accepted Answer

The difference in mass of a nucleon when outside an atomic nucleus compared to inside the nucleus is dependent on the atomic number of the nucleus. This is because the strong nuclear force that holds the nucleons together in the nucleus is much stronger than the electromagnetic force between protons in the nucleus. As the atomic number of the nucleus increases, the number of protons and hence the electromagnetic force also increases, causing a greater difference in mass between a nucleon inside and outside the nucleus.
