    Atomic hydrogen is excited to the \[{{\text{n}}^{\text{th}}}\] energy level. The maximum number of spectral lines which it can emit while returning to the ground state is

    A)  \[\frac{1}{2}n(n-1)\]                                     

    B)  \[\frac{1}{2}n(n+1)\]

    C)  \[n(n-1)\]                          

    D)  \[n(n+1)\]

    Correct Answer: A

    Solution :

    Maximum number of emissive spectral lines, when an electron returns from nth  orbit to ground energy state are \[=\frac{n(n-1)}{2}\]
