Chapter 16, Problem 62APP

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:

  $\begin{array}{l}\text{potassium-40 (β decay)}\\ \text{sulfur-35 (β decay)}\\ \text{platinum-190 (α decay)}\\ \text{Ra-210 (α decay)}\\ \text{In-113m (γ emission)}\end{array}$
