    The magnetic moment (in BM) of\[Z{{n}^{2+}}\]ion according to spin-only formula is:

    A)  zero                                     

    B)  1.73

    C)  2.84                                      

    D)  3.87

    Correct Answer: A

    Solution :

                    \[Z{{n}^{2+}}(Z=30):[Ar]\,3{{d}^{10}}4{{s}^{0}};\]zero unpaired\[{{e}^{-}}\]. Hence, its magnetic moment is zero. \[\mu =\sqrt{n(n+2)}=\sqrt{0(0+2)}\] \[\mu =0\]
