The energy of an electron in n=3 orbit will be "-1.52 eV". A complete solution is provided below.
The given values are:
As we know,
The energy of orbital in [tex]n^{th}[/tex] shell will be:
→ [tex]E_n = \frac{-13.6}{n^2 \ eV}[/tex]
By substituting the values, we get
→ [tex]= -\frac{13.6}{3^2 \ eV}[/tex]
→ [tex]= -\frac{13.6}{9 \ eV}[/tex]
→ [tex]= -1.52 \ eV[/tex]
