    Which of the following is not permissible arrangement of electrons in an atom?

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

    B) \[n=4,l=0,m=0,s=-1/2\]

    C) \[n=5,l=3,m=0,s=+1/2\]

    D) \[n=3,l=2,m=-3,s=-1/2\]  

    Correct Answer: D

    Solution :

     If \[n=3\] \[l=0\]to \[(3-1)=0,1,2\] \[m=-l\]to \[l=-2,-1,0,+1,+2\] \[s=\pm \frac{1}{2}.\]s \[\therefore \]Option [d] is not a permissible set of quantum number.
