Chapter 18.3, Problem 18.3E

Interpretation Introduction

Interpretation:

Binding energy per nucleon for the lithium-6 and helium-4 has to be calculated and the nucleus that is more stable has to be identified.

Concept Introduction:

Binding energy is a short strong force that is present in the nucleus which holds the protons together by overcoming the electrostatic repulsive forces between them.  Whenever there is a change in energy, a corresponding change in mass is also observed and this can be given by the equation shown below,

    $\Delta E=(\Delta m)c^2$

When more particles combine to form nuclear there is a great change in mass and energy.  The nuclear stabilities can be compared more appropriately by dividing the binding energy of nucleus with the number of nucleons.  The result obtained is the binding energy per nucleon.  Protons and neutrons are known as nucleons.  Binding energy is represented as $E_b$.
