Chapter 16, Problem 59APP

Interpretation Introduction

Interpretation:

The type of radioactive decay needs to be identified.

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:

  ${}_{\text{13}}^{\text{27m}}\text{Al}\to {}_{\text{13}}^{\text{27}}\text{Al}\text{+}{}_{\text{0}}^{\text{0}}\text{γ}$

  ${}_{\text{5}}^{\text{8}}\text{B}\to {}_{\text{4}}^{\text{8}}\text{Be}{\text{+ }}_{\text{1}}^{\text{0}}\text{e}$

${}_{\text{5}}^{\text{8}}\text{B}\to {}_{\text{4}}^{\text{8}}\text{Be}{\text{+ }}_{\text{1}}^{\text{0}}\text{e}$

${}_{\text{86}}^{\text{220}}\text{Rn }\to {}_{\text{84}}^{\text{216}}{\text{Po + }}_{\text{2}}^{\text{4}}\text{He}$
