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. 1.9 eV
C. 11.1 eV
D. 13.6 eV

Explanation

The energy of `n^("th")` orbit of hydrogen atom is given as
`E_(n)=-(13.6)/(n^(2))eV`
`therefore" "E_(1)=-13.6eV, E_(2)=-(13.6)/(2^(2))=-(13.6)/(2^(2))=-2.3eV`
`E_(3)=-(13.6)/(3^(2))=-1.5eV, E_(4)=-(13.6)/(4^(2))=-(13.6)/(4^(2))=-0.85eV`
`therefore" "E_(3)-E_(2)=-1.5-(-3.4)=1.9eV`
`E_(4)-E_(3)=-0.85-(-1.5)=0.65eV`
