Nuclei (part-2)

What is the importance Nuclear force? What is the strongest force in nature? How does the nuclear force changes with the nuclear separation between the two nucleons? When are heavy and light nuclei more stable? What kinds of nuclei are more stable?

Inside the nucleus there are positively charged particle proton and neutral charged particle neutron. Positively charged particle repel each other still the nucleons bind together, they have strong force of attraction between them. Nuclear force is defined as the force between any two nucleons is called nuclear force. It can be force between proton, neutron proton, and neutron. Nuclear force is always attractive and is independent of charge. It is the strongest force in nature. It is a short range force. More bind energy more stable is the nucleus. Lighter nuclei are more stable if the number of neutron and proton are more stable. Heavy nuclei are more stable if neutron are more than proton. Nuclei having even number of proton or even number of neutron or both are more stable
