    An electron in the n = 1 orbit of hydrogen atom is bound by 13.6 eV. If a hydrogen atom is in the n = 3 state, how much energy is required to ionize it                              [MP PMT 1995]

    A)            13.6 eV                                   

    B)            4.53 eV

    C)            3.4 eV                                      

    D)            1.51 eV

    Correct Answer: D

    Solution :

               Required energy \[{{E}_{3}}=\frac{+13.6}{{{3}^{2}}}=1.51eV\]
