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

    A) \[n=5,\,\,l=3,\text{ }m=0,\text{ }s=+\,1\text{/}2\]

    B) \[n=3,\text{ }l=2,\text{ m}=-\,3,\text{ }s=-1/2\]

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

    D) \[n=4,\text{ }l=0,\text{ m}=0,\text{ }s=-1/2\]

    Correct Answer: B

    Solution :

    [b] \[m=-l\] to \[+l\], through zero thus for \[l=2\], values of m will be \[-2,-1,0,+1,+2.\] Therefore for \[l=2\], m cannot have the value -3.
