Question

Heavy stable nuclei have more neutrons than protons. This is because of the fact that.

Options

• neutrons are heavier than protons

• electrostatic force between protons are repulsive

• neutrons decay into protons through beta decay

• nuclear forces between neutrons are weaker than that between protons

Answer 1

Electrostatic force between protons are repulsive

Explanation:

Electrostatic force between proton is repulsive which causes the instability of nucleus. Neutrons are neutral and help to balance the repulsive forces. So more neutrons maintain better stability.
