The enregy, radius and velocity of the electron in the hydrogen atom in the ground state are `-13.6 eV, 0.53 Å` and `2.188 xx 10^(8) m s^(-1)` respectively.
If the electron absorbs `12.1 eV` of energy, it will jump to the orbit

Options

A. 2nd
B. 3rd
C. 4th
D. 5th

Answer

B

Explanation

Energy of electron after absorption
=-13.6eV+12.1 eV=-15.6 eV
For hydrogen , `E_(n)=(-13.6)/(n^(2))`
`:. 1.5=13.6/(n^(2))` or `n^(2) =9` or n=3
