    Which one of the following is the set of correct quantum numbers of an electron in 3d orbital?

    A) \[n=3,l=0,m=0,s=-1/2\]

    B) \[n=2,l=3,m=0,s=+1/2\]

    C) \[n=3,l=1,m=0,s=-1/2\]

    D) \[n=3,Z=2,m=1,s=+\text{ }1/2\]

    Correct Answer: D

    Solution :

                     For 3d orbital, \[n=3\] For d orbital, \[l=2\] and         \[m=-2,-1,0,+1,+2\] \[s=\pm \frac{1}{2}\] \[\therefore \]The correct set for 3d orbital is \[n=3,l=2,m=1\,,\,s+\frac{1}{2}\]
