    The correct set of the four quantum numbers of a 4d electron is:

    A)  \[4,2,1,-\frac{1}{2}\]                     

    B)  \[4,2,1,0\]

    C)  \[4,3,2,+\frac{1}{2}\]                    

    D) \[4,3,-2,+\frac{1}{2}\]

    Correct Answer: A

    Solution :

                    For 4d-electron the four quantum numbers are as: \[n=4\] \[l=2\] \[m=-2,-1,\text{ }0,+1,+2\] \[S=\pm \frac{1}{2},\pm \frac{1}{2},\pm \frac{1}{2},\pm \frac{1}{2},\pm \frac{1}{2}\]
