The Bohr's energy equation for H atom reveals that the energy level of a shell is given by

E = - 13.58/{n^2}\;\mathrm{eV}.

The smallest amount that an H-atom will absorb, if in ground state is:

View answer and explanation

Correct option: D

10.19 eV

Option D (10.19 eV) is correct because it represents the energy difference between the ground state (n=1) and the first excited state (n=2) of the hydrogen atom.
