Chapter 9.2, Problem 9.9P

(a)

Interpretation Introduction

Interpretation:

The balanced nuclear reaction for the beta emission of ${{}_{\text{9}}}^{\text{20}}\text{F}$ has to be given.

Concept Introduction:

Beta decay reaction:

Beta particles are electrons (electrons with negative electric charge). Beta decay occurs when in a nucleus with too many protons or too many neutrons, one of the protons or neutrons are transformed into the other.
