Chapter 20.2, Problem 2PPB

Interpretation Introduction

Interpretation:

Mass of ${}_{\text{79}}^{\text{197}}\text{Au}$ should be determined.

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

To determine: Mass of ${}_{\text{79}}^{\text{197}}\text{Au}$
