... The n-n, n-p, and p-p nuclear forces are all almost identical. (There are some important differences.) Of course, there is an additional p-p Coulombic repulsive potential, but that is separate from the nuclear force. Owing to these nuclear forces between individual nucleons, a nucleus is tightly bou ...
