Increase in no of Nuetrons decrease the polarizing power of the nucleus(Consider keeping charged spheres and neutral conducting spheres in between them which distorts the interaction (attractive/repulsive) between the charged spheres Effectively decreasing the polarizing power of the positively charged spheres(protons) Hence the lesser pull is in the nucleus with lesser neutrons
