Chapter 16, Problem 61APP

Interpretation Introduction

Interpretation:

The balanced chemical equation for the given nuclear reaction needs to be determined.

Concept introduction:

• Alpha decay happens when a nucleus emits an alpha particle ${\text{α}}_{\text{2}}^{\text{4}}$ .
• Beta decay happens when a nucleus emits a beta particle identical to the electron ${\text{e}}_{\text{-1}}^{\text{0}}$ .
• Positron emission happens when a nucleus emits a positron ${\text{e}}_{\text{1}}^{\text{0}}$ .
• Gamma decay is a loss of energy by the nucleus it is denotes as ${\text{γ}}_{\text{0}}^{\text{0}}$ .

Given:

  $\begin{array}{l}\text{Th-225 (α decay)}\\ \text{Bi-210 (α decay)}\\ \text{cesium-137 (β decay)}\\ \text{tin-126 (β decay)}\\ {\text{F-18 (β}}^{\text{+}}\text{ emission)}\end{array}$
