The heavier nuclei tend to have larger `N//Z` ratio because

A

coulomb forces have longer range compared to the nuclear forces

B

a neutron does not exert electric repulsion

C

a neutron is an unstable particle

D

a neutron is heavier than a proton

Text Solution

Verified by Experts

The correct Answer is:
A, B

`N//Z` ratio increases in heavier nuclei becuase coulomb forces have longer range compared to nuclear forces and neutron exerts no electric repulsion.
