Chapter 19, Problem 19.21QP

Interpretation Introduction

Interpretation: The mode of decay of $\text{iodine}-137$ to form the isotopes of the given elements is to be identified.

Concept introduction: On beta decay, the atomic number increases by one and the mass number remains same.

To determine: The mode of decay of $\text{iodine}-137$ to form $\text{xenon}-137$ followed by $\text{cesium}-137$.
