Chapter 20.1, Problem 5R

To determine

To Calculate: The approximate ratio of protons to neutrons in the nucleus of $\mathrm{Radon}-222$ .

Answer to Problem 5R

  $0.63235$

Explanation of Solution

Given information:

The number of protons and the number of neutrons in the nucleus of $\mathrm{Radon}-222$ is $86$ and $136$ respectively.

Calculation:

Calculate the ratio of number of protons to neutrons.

  $\begin{array}{c}\mathrm{ratio}=\frac{86}{136}\\ =0.63235\end{array}$

Conclusion:

Thus, the required ratio is $\frac{86}{136}$ which is $0.63235$ .
