Question

Relation between binding energy and mass effect?​

Answer 1

Answer:

Nuclear binding energy is the energy required to split an atom's nucleus into protons and neutrons. Mass defect is the difference between the predicted mass and the actual mass of an atom's nucleus. The binding energy of a system can appear as extra mass, which accounts for this difference.

Answer 2

Answer:

Mass defect: It is found that mass of a stable nucleus is alway less than the sum of masses of its constituent protons and neutrons in their free state.

Consider the Nucleus

X^Az

It has Z protons (A-Z) neutrons, therefore its mass defect will be

Δm=Zmp +(A−Z)mmn-

Expression for binding energy: The nucleus XAz

contains Z protons and (A−Z) neutrons.

Its mass defect is

Δm=Zmp +(A−Z)mn-mN

Where mN→ mass of nucleus

ΔEb =Δm×c 2=[ZZm +(A−Z)mp −mN ]c2

Mass defect always improve binding energy of nucleus. For mass defect is more stable nucleus
