Chapter 20.2, Problem 2PPC

Interpretation Introduction

Interpretation:

For the given graphs, it should the selected the graph that represents the relationship between energy released and mass defect.

Concept Introduction:

• Energy required to break the nucleus into its corresponding proton and neutron is called nuclear binding energy
• This quantity represents the conversion of mass to energy occurs during an exothermic reaction.
• Nuclear binding energy can be calculated by Einstein’s mass energy equivalence relationship that is, $\Delta E=\left(\Delta m\right)c^2$

• Where, $\left(\Delta m\right)$ is called mass defect.

• The difference between mass of an atom and the sum of the masses of its proton, electron, and neutron is called Mass defect
