Chapter 18, Problem 16E

Interpretation Introduction

Interpretation:

The parent nuclide that disintegrates into lead $\text{-207}$ and beta particle in the last step of the radioactive decay series of uranium $\text{-235}$ is to be stated.

Concept introduction:

Heavy atoms have unstable nuclei. Due to which they are radioactive and disintegrate into smaller nuclei. The decay of radioactive nuclei can be done by alpha particle emission, beta-particle emission, positron decay, gamma decay, and electron capture.
