Chapter 15, Problem 40QP

Interpretation Introduction

Interpretation:

The $\frac{N}{Z}$ ratio for elements $80$ to $90$ is to be given.

Concept Introduction:

The ratio of neutrons to protons, $\frac{N}{Z}$ is helpful in predicting nuclear stability. Stable nuclides have an $\frac{N}{Z}$ ratio of 1.

The stability of a nucleus can be correlated to its $\frac{N}{Z}$ ratio. For the first twenty elements, having low atomic numbers, the stable isotopes are those with an $\frac{N}{Z}$ ratio of $1$ .
