    In the following atoms and moleculates for the transition from n= 2  to n = 1, the spectral line of minimum wavelength will be produced by                                      [IIT 1983]

    A)            Hydrogen atom                  

    B)            Deuterium atom

    C)            Uni-ionized helium            

    D)            di-ionized lithium

    Correct Answer: D

    Solution :

                       \[\frac{1}{\lambda }=R{{Z}^{2}}\left( \frac{1}{{{1}^{2}}}-\frac{1}{{{2}^{2}}} \right)\] For di-ionized lithium the value of Z is maximum.
