    Assertion (A): The spin only magnetic moment of \[S{{c}^{3+}}\]is 1.73 BM. Reason (R): The spin only magnetic moment (in BM) of an ion is equal to \[\sqrt{n(n+2)},\] where \[n\] is the number of unpaired electrons present in the ion. The correct answer is:

    A)  both (A) and (R) are true and (R) is the correct explanation of

    B)  both (A) and (R) are true and (R) is not the correct explanation of

    C) (A)  is true but (R) is not true

    D) (A)  is not true but (R) is true

    Correct Answer: D

    Solution :

    \[_{21}S{{c}^{3+}}=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}}3{{p}^{6}}\] Number of unpaired electrons \[(n)=0\] Hence, spin only magnetic moment i.e., \[\mu =\sqrt{n(n+2)}\] = 0
