Two nuclei have mass number in the ratio 1:8. What is the ratio of their nuclear radii?

Explanation

To solve the problem of finding the ratio of the nuclear radii of two nuclei with mass numbers in the ratio 1:8, we can follow these steps:

### Step 1: Define the Mass Numbers
Let the mass number of the first nucleus be \( A_1 \) and the mass number of the second nucleus be \( A_2 \). According to the problem, we have:
\[ \frac{A_1}{A_2} = \frac{1}{8} \]
This implies:
