Chapter 16, Problem 66APP

Interpretation Introduction

Interpretation:

The balanced chemical equation for the given radioactive reactions needs to be determined.

Concept introduction:

• The mass number of the atoms on the left must be equal to the mass number of the atoms on the right.
• The atomic number of the atoms on the left must be equal to the mass number of the atoms on the right.
• 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 ${\text{γ}}_{\text{0}}^{\text{0}}$ .
