• B) The neutrons in the nucleus shield the protons from each other.
• C) The Coulomb force does not operate within nuclei.
• D) The gravity of the protons and neutrons overcomes their repulsion at such close distances.
• E) There are an equal number of electrons in the nucleus which neutralize the protons.
