Using Bohr theory, calculate the radii of the first and the tenth orbits in the hydrogen atom

Explanation

To calculate the radii of the first and tenth orbits in a hydrogen atom using Bohr's theory, we can follow these steps:

### Step 1: Understand the Formula
According to Bohr's theory, the radius of the nth orbit (Rn) is given by the formula:
\[ R_n = \frac{0.53 \, n^2}{Z} \, \text{Å} \]
where:
- \( R_n \) is the radius of the nth orbit,
- \( n \) is the principal quantum number (orbit number),
