From the given data , calculate the energy of an electron in the second Bohr orbit of an excited hydrogen atom.

Explanation

To calculate the energy of an electron in the second Bohr orbit of an excited hydrogen atom, we can use the formula for the energy of an electron in the nth orbit of a hydrogen atom:

### Step 1: Write down the formula for the energy of an electron in the nth orbit.
The energy \( E_n \) of an electron in the nth orbit of a hydrogen atom is given by the formula:
\[ E_n = -\frac{13.6 \, \text{eV} \cdot Z^2}{n^2} \]
where:
