Answer :

(i) The stablilty of Sn>Sb.



The equation for the proton seperation energy is given as ; The atomic mass is given for In=118.9058u, Sn=119.902199u, Sb=120.903824u, H=1.0078252u.

Formula Used

Separation Energy: The energy required to remove a single proton from a tightly bound nucleus. The formula given in the question is


Seperation Energy, Atomic mass of Z-1 element, atomic mass of Hydrogen, Atomic mass of Z element. c is the speed of light.

Therefore, the seperation energy for is

And the Seperation Energy for Sb is

As you can see that the value of seperation energy for Sn>Sb, Hence, the stablilty of Sn>Sb.

(ii) Magic number in mordern physics states that the nucleons are arranged in same way as orbit are arranged in an atom. The existance of magic number states similiarity of structure of orbits in a nucleus is same as that of orbit structure in an atom, which in turns tell us that such types of nucleus also have a higher binding energy per nucleon in a nucleus.
