Chapter 17, Problem 20E

Interpretation Introduction

Interpretation:

The parent nuclides and daughter nuclides in the given nuclear equation are to be identified. Along with this, the type of radioactive decay involved in the given reaction is to be determined.

Given information: The given nuclear reaction is:

${}_{\text{91}}^{\text{231}}\text{Pa}{\to }_{\text{89}}^{\text{231}}\text{Ac}{+}_{\text{2}}^{\text{4}}\text{He}$

Concept introduction:

The original atom before a radioactive decay is the parent nuclide.

The daughter nuclides are the products obtained after the radioactive decay.
