    The ionisation energy of 10 times ionised sodium atom is [DPMT 1991]

    A)            13.6 eV                                   

    B)            \[13.6\times 11\ eV\]

    C)            \[\frac{13.6}{11}eV\]        

    D)            \[13.6\times {{(11)}^{2}}eV\]

    Correct Answer: D

    Solution :

               (Eion)Na\[={{Z}^{2}}{{({{E}_{ion}})}_{H}}={{(11)}^{2}}13.6\ eV\]
