Nuclei tend to have more neutrons than protons at high mass numbers because
1 Neutrons are neutral particles
2 More neutrons minimize the coulomb repulsion
3 Neutrons have more mass than protons
4 Neutrons decrease the binding energy
Explanation:
Since neutrons are uncharged but their mesonic exchanges, with protons and neutrons itself contribute to stability, [It has limited application].
