Explanation

The binding energy per nucleon is maximum for nuclei with mass number around 60, such as iron (Fe-56). This is because the strong nuclear force, which binds the nucleons together, is most effective at this mass range, resulting in a higher binding energy per nucleon.

Isotopes are atoms having

Explanation

(a) For isotopes Z is same and A is different. Therefore the number of neutrons A-Z will also be different.

The mass of an α-particle is

Explanation

(a) This is due to mass defect because a part of mass is used in keeping the neutrons and protons bound as α-particle.

Atomic number of a nucleus is Z and atomic mass is M. The number of neutron is
