Chapter 24, Problem 6STP

Interpretation Introduction

Interpretation:

The ${}_{\text{30}}^{\text{70}}\text{Zn}$ isotopes undergoes to which process is to be explained.

Concept introduction:

The beta negative decay is the decay in which neutron is converted into proton while the process creates the electron and an electron antineutrino.

Answer to Problem 6STP

Correct answer:

Option A. It undergoes the beta decay.

Explanation of Solution

Reason for correct option:

Basically there are two types of beta decay: beta positive and beta negative decay.

The beta negative decay is the decay in which neutron is converted into proton while the process creates the electron and an electron antineutrino.

So, ${}_{\text{30}}^{\text{70}}\text{Zn}$ undergoes beta negative decay.

Conclusion

Reasons for incorrect options:

B. No, it undergoes beta negative decay.

C. No, it is lighter element so it not undergoes to nuclear fusion.

D. No, the stability of ${}_{\text{30}}^{\text{70}}\text{Zn}$ is lies on the stability line so it not undergoes to positron emission.
