WebNeutral carbon-14 contains six protons, eight neutrons, and six electrons; its mass number is 14 (six protons plus eight neutrons). These two alternate forms of carbon are isotopes. Some isotopes are stable, but … 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.
