Chemistry Question on Structure of atom

Which of the following is the energy of a possible excited state of hydrogen?

A

+13.6eV+ \,13.6\, eV

B

6.8eV-6.8 \, eV

C

3.4eV-3.4\, eV

D

+6.8eV+ 6.8\, eV

Answer

3.4eV-3.4\, eV

Explanation

Solution

13.6z2n2-\frac{13.6 z^{2}}{n^{2}}
\Rightarrow for hydrogen ;z=1; z=1
13.6n2-\frac{13.6}{n^{2}}
Possible is 13.6,3.4,1.5-13.6,-3.4,-1.5 etc.

So, the correct option is (C): 3.4eV-3.4\, eV
