Chapter 14, Problem 14.48PAE

Interpretation Introduction

Interpretation: The isotope of tin is ${}^{\text{132}}\text{Sn}$, has a magic number of neutrons as well as a magic number of neutrons, but it is unstable. 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.
