The dependence of binding energy per nucleon, `B_N` on the mass number, `A` is represented by.
(a) , (b) ,
( c) , (d) .

Options

A.
B.
C.
D.

Answer

A

Explanation

The graph showing that greater the binding energy per nucleon, the more stable the nucleus is.The graph has its maximum of 8.8 MeV/nucleus when the number of nucleons is 56. The nucleus that has 56 protons and neutron is `""_(26)^(56)Fe` , an iron isotope . This is the most stable nucleus of them all , since maximum energy is needed to pull a nucleon away from it.
