Question

Heavy stable nuclei have more neutrons than protons. this is because of the fact that(a) neutrons are heavier than protons(b) electrostatic force between protons are repulsive(c) neutrons decay into protons through beta decay(d) nuclear force between neutrons are weaker than that between protons

Answer 1

hope this helps you

Answer 2

Answer:

(b). Electrostatic force between the protons are repulsive.

Explanation:

Heavy stable nuclei have more neutrons than protons. The reason is the protons, being charged particles, repel each other. As to get to heavier elements, with each new proton you add, there is a larger repulsive force.

The nuclear force is attractive and stronger than the electrostatic force but it has a finite range.

So you need to add extra neutrons, which do not repel each other, to add extra attractive force. You eventually reach a point where the nuclear is too big and tends to decay via alpha decay or spontaneous decay.
