Chapter 14, Problem 14.45PAE

Interpretation Introduction

Interpretation:

${}^{\text{164}}\text{Pb}$ nuclide is not stable. Explain

Concept introduction: Neutron, Proton ratio is used to determine the stability of isotope.

If the $\frac{\text{N}}{\text{Z}}$ ratio is too high −Neutrons are converted into protons via $\text{β}$ -decay

If the $\frac{\text{N}}{\text{Z}}$ ratio is too low−Protons are converted into neutrons via positron emission or electron capture.
