If two atoms of the same elements share the same number of protons but differ in several neutrons, they form isotopes. And most of the atoms are stable. The "box" is provided by the confining electromagnetic force exerted by the nucleus on the electron. The nucleus is surrounded by negatively charged particles called electrons which form a cloud around it. I can't give you a real answer but I figured this may be better than nothing: Because the interaction energies inside the nucleus are very low, and when we perform experiments on nucleons at those energies they behave primarily as discrete particles.
