    The correct set of quantum numbers for unpaired electron of fluorine is:

    A)  \[n=3,l=1,\,m=0\]

    B)  \[n=2,l=1,\text{ }m=0\]

    C)  \[n=2,l=0,m=0\]

    D)  \[n=2,l=1,\text{ }m=1\]

    Correct Answer: D

    Solution :

                    \[_{9}F:1{{s}^{2}},2{{s}^{2}}2{{p}^{5}}or1{{s}^{2}},2{{s}^{2}},2p_{x}^{2},2p_{y}^{2},2p_{z}^{1}\] Quantum numbers for\[2p_{z}^{1}\]are as: \[n=2,\,\,l=1,\,\,\,m=+1\]
