    Which of the following represents the correct sets of the four quantum numbers of 4 d electrons?

    A)  \[4,\text{ }3,\text{ }2,+\frac{1}{2}\]      

    B) \[4,\text{ }2,\text{ }1,\text{ }0\]

    C)   \[4,\text{ }3,\text{ }-2,+\frac{1}{2}\]                    

    D) \[4,\text{ }2,\text{ }1,-\frac{1}{2}\]

    Correct Answer: D

    Solution :

                     For 4d electrons: \[n=4,\]for d sub-shell\[l=2\] Hence, m can be\[-2,\text{ }-1,\text{ }0\text{ }+1,\text{ }+2\]and s either\[+\frac{1}{2}\]and\[-\frac{1}{2}\]
