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 forces between neutrons are weaker than that between protons

Text Solution

Verified by Experts

The correct Answer is:
B
Stable heavy nuclei have more neutrons than protons. This is because electrostatic force between protons is repusive which may reduce stability.
