  • #4
    Is it easier to take out a nucleon (a) from carbon or from iron (b) from iron or from lead?
    Ans : Binding energy per nucleon of a nucleus is defined as the energy required to break-off a nucleon from it. (a) As the binding energy per nucleon of iron is more than that of carbon, it is easier to take out a nucleon from carbon than iron. (b) As the binding energy per nucleon of iron is more than that of lead. Therefore, it is easier to take out a nucleon from lead as compared to iron.
