Chapter 25, Problem 31PS

(a)

Interpretation Introduction

Interpretation:

Out of the given nuclei that undergoes ${}_{\text{-1}}^{\text{0}}\text{β}$ has to be identified.

Concept-Introduction:

Beta decay series is two types such as beta minus decay and beta plus decay.

The neutron is converted to a proton in this process it create an electron is called beta minus decay radiation. Beta decay generally occurs in neutron-rich nuclei.

Interpretation Introduction

Interpretation:

Out of the given nuclei that undergoes ${}_{\text{+1}}^{\text{0}}\text{β}$ has to be identified.

Concept-Introduction:

Beta decay series is two types such as beta minus decay and beta plus decay.

The neutron is converted to a proton in this process it create an electron is called beta minus decay radiation.

Then beta plus decay radiation, in this process proton converted to neutron it creates a positron. So these are called positron emission. Positron emission takes place when the ratio of neutron to proton is low. Or generally occurs in proton-rich nuclei.
