Chapter 17, Problem 61E

Interpretation Introduction

Interpretation:

For the each of the given nuclide, nuclear equation for the beta decay is to be written.

Concept introduction:

Beta radiation is a consequence of emission of an electron from an unstable nucleus.

The symbol of beta particle is denoted as $\text{e}$.

The beta radiation can be represented by the nuclear reaction as follows:

$\underset{\text{parent nuclide}}{\underbracket{\text{R}\text{a}}}\to \underset{\text{Daughter nuclides}}{\underbracket{\text{T}\text{h}+\text{e}}}$

The atomic number of an atom increases 1 unit, which implies the addition of proton.
