To which orbit the electron in the hydrogen atom will jump on absorbing 12.1 eV of energy? |
|
Answer» Solution :ENERGY of ELECTRON in the nth ORBIT of H-atom is `E_(N) = (-13.6)/(n^(2)) eV :. E_(1) = -13.6 eV` After absorbing 12.1 eV, the energy will be `= -13.6 + 12.1 eV = -1.5 eV` THUS, `(-13.6)/(n^(2)) = - 1.5 eV or n^(2) = 9 or n = 3` Thus, electron will jump to 3rd orbit. |
