Question:

For small nuclei, an equal number of protons and neutrons gives rise to a stable nucleus. However, for larger nuclei, an excess of neutrons is required. Using your knowledge of the relevant physics, discuss why additional neutrons make one of these larger nuclei more stable.

Nuclear Physics:

The force that binds together nuclei of atoms is called a strong nuclear force. It is the strongest of four fundamental forces of nature and is responsible for the confinement of quarks in the protons, neutrons, and mesons. The force range is very short and it quickly decreases so that any appreciable strong interaction exists only on the distances comparable with the size of proton.
