                    Consider die following sets of quantum numbers:                                                                                                            \[n\]      \[l\]       \[m\]     \[s\]                 (i)            3              0              0              \[+1/2\]                 (ii)           2              2              1              \[+1/2\]                 (iii)          4              3              -2            \[-1/2\]                 (iv)         1              0              -1            \[-1/2\]                 (v)          3              2              3              \[+1/2\]                 Which of the following sets of quantum number is not possible?                                                              

    A)                 ii, iii and iv           

    B)                 i, ii, iii and iv       

    C)                 ii, iv and v

    D)                 i and iii

    Correct Answer: C

    Solution :

                    The value of l varies from 0 to n ? l  and the value of m varies from -l to +l through zero.                 The value of \['s'\pm \frac{1}{2}\]which signifies the spin of electron. The correct sets of quantum number are following:                                 n             l               m            s                 (ii)           2              1              1              +1/2                 (iv)         1              0              0              -1/2                 (v)          3              2              2              + 1/2
