Chapter 18, Problem 14E

Interpretation Introduction

Interpretation:

The parent nuclide that disintegrates into the lead $\text{-206}$ and an alpha particle in the last step of the radioactive decay series of uranium $\text{-238}$ is to be stated.

Concept introduction:

Heavy atoms have unstable nuclei. Due to which they are radioactive and disintegrates into smaller nuclei. The decay of radioactive nuclei occurs by various types of processes such as alpha particle emission, beta-particle emission, positron decay, gamma decay, and electron capture.
