2011 · Q85

NEETPhysicsAtoms and NucleiMCQ+4 / −1
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?
  1. A
    0.65 eV
  2. B
    1.9 eV
  3. C
    11.1 eV
  4. D
    13.6 eV

Correct answer: C

En = −13.6n2 - {{13.6} \over {{n^2}}}−n213.6​

∴\therefore∴ E1 = –13.6 eV

E2 = –3.4 eV

E3 = –1.5 eV

E4 = –0.85 eV

∴\therefore∴ E3 – E2 = –1.5 – (–3.4) = 1.9 eV

E4 – E3 = –0.85 – (–1.5) = 0.65 eV

Obviously, difference of 11.1 eV is not possible.
