Chapter 11.5, Problem 11.10P

a)

Interpretation Introduction

Interpretation:

The positrons radioactive isotope in the diagram has to be identified.

Concept introduction:

Beta decay:

The $\text{β}$ emission includes the decomposition of a neutron to yield an electron and a proton.

${}_{\text{0}}^{\text{1}}\text{n}{\to }_{\text{1}}^{\text{1}}{\text{P+}}_{\text{-1}}^{\text{0}}\text{e}$

Where the electron $\left({}_{\text{-1}}^{\text{0}}\text{e}\right)$ is emitted as a $\text{β}$ particle and the proton is taken by the nucleus

b)

Interpretation Introduction

Interpretation:

The balanced nuclear decay reactions have to be written.

Concept introduction:

Beta decay:

The $\text{β}$ emission includes the decomposition of a neutron to yield an electron and a proton.

${}_{\text{0}}^{\text{1}}\text{n}{\to }_{\text{1}}^{\text{1}}{\text{P+}}_{\text{-1}}^{\text{0}}\text{e}$

Where the electron $\left({}_{\text{-1}}^{\text{0}}\text{e}\right)$ is emitted as a $\text{β}$ particle and the proton is taken by the nucleus

Balanced nuclear reaction:

For a balanced nuclear equation the mass number and atomic number on the both sides of the reaction should be equal.
