Chapter 25, Problem 16PS

Interpretation Introduction

Interpretation:

The equation is to be written for the radioactive decay series Thorium-232 to Pb-207.

Concept introduction:

In this radioactive decay process the unstable isotopes loses their energy by emitting radiation. It is converted in to stable isotopes. The emitting radiations are Alpha emission and Beta emission.

β − decay (electron emission): ${}_{\text{-1}}^{\text{0}}\text{β}$

α − decay (Helium nuclei emission): ${}_{\text{2}}^{\text{4}}\text{He}$
