Massive nuclear particles engage in the strong nuclear force.........


At short ranges (and nuclear ranges are short, #~=10^-15m#), nucleons, protons and neutrons, engage in the strong nuclear force, one of the four known, fundamental interactions. This is approx. #10^2# times stronger than the electromagnetic force (and it needs to be, why?).

Anyway, if you want a more sofisticated answer, you will have to find a particle physicist. Most chemists, including me, do not have too much clue about this force.
