Ravi G · Accepted Answer

Binding energy is the measure of nucleous stability More stable
nucleus , more the binding energy per nucleon
As mass no increases, no of protons increases due to which
repulsive force between the protons increases and nucleus become
less stable
Hence Binding energy per nucleon decreases
