Chapter 20, Problem 70AP

Interpretation Introduction

Interpretation:

The radioactive chemical reaction in which $\text{N-18}$ can achieve stability is to be represented.

Concept introduction:

The stability of a particular nuclei depends on the neutron(n) to proton(p) ratio($\frac{n}{p}$).

Those nuclei whose neutron to proton ratio is close to 1 are stable, as this ratio deviates from 1, the nuclei becomes unstable.

The deviation of the neutron to proton ratioarises at higher atomic numbers because more neutrons are required to counterbalance the repulsion forces among the protons.
