Radioactivity - Mrs. Sjuts` Science Site
... Protons and neutrons are held together less tightly in large nuclei. Why? Small nuclei have few protons, so the repulsive force on a proton due to other protons is small In a large nuclei, the attractive strong force is exerted only by the nearest neighbors. All the protons exert repulsive forces ma ...
