Chapter 21, Problem 21.28QP

(a)

Interpretation Introduction

Interpretation: The mode of radioactive decay for the given isotopes is to be identified.

Concept introduction: The nuclide that lies above the green belt in the graph of belt of stability, are nuclear rich and those that lie below the green region is nuclear poor. Green nuclide represents stable nuclides and orange nuclide represents unstable nuclide.

The isotopes that are nuclear rich undergo beta emission.

The isotopes that are nuclear poor undergo positron emission or electron capture.

To determine: The mode of radioactive decay of ${}^{24}\text{Ne}$.

(b)

Interpretation Introduction

To determine: The mode of radioactive decay of ${}^{38}\text{K}$.

(c)

Interpretation Introduction

To determine: The mode of radioactive decay of ${}^{45}\text{Ti}$.

(d)

Interpretation Introduction

To determine: The mode of radioactive decay of ${}^{237}\text{Np}$.
