Out of the following which one is not a possible energy for a photon to be emitted by hydrogen atom according to Bohr's atomic model?

Options

A. 0.65eV
B. 1.9eV
C. 11.1eV
D. 13.6eV

Answer

C

Explanation

The energy of `n^(th)` orbit of hydrogen atom is given as
`E_n=-(13.6)/(n^2)eVthereforeE_1=-13.6eV`
`rArrE_2=-(13.6)/(2^2)=-3.4rArrE_3=-(13.6)/(3^(2))=-1.5eV`
`E_4=-(13.6)/(4^2)=-0.85`
`E_3-E_(2)=-1.5-(-3.4)=1.9eV`
`E_4-E_(3)=-0.85-(-1.5)=0.65eV`
