Physics · Nuclei
Heavy stable nuclei have more neutrons than protons. This is primarily because:
- 1nuclear forces between neutrons are weaker than those between protons.
- 2neutrons decay into protons through beta decay.
- 3electrostatic forces between protons are repulsive and require more neutrons to provide attractive nuclear forces.✓
- 4neutrons are heavier than protons.
Correct answer
electrostatic forces between protons are repulsive and require more neutrons to provide attractive nuclear forces.
