    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 : \[n=4\] \[l=1\] \[m=-2,-1,0,+1,+2\] \[s=\pm \frac{1}{2},\pm \frac{1}{2},\pm \frac{1}{2},\pm \frac{1}{2},\pm \frac{1}{2}\]
