How many protons are there if the atomic number of Carbon is … WebBoth neutrons and protons carry the strong force (but electrons do not). The strong force is what binds the nucleus together, by overcoming the repulsion between the protons. But an atom must have just the right balance of protons to neutrons to make a stable nucleus. If there are too few or too many neutrons, the nucleus won't be stable.
