        The highest magnetic moment is shown by the transition metal ion with the configuration

    A)  \[3{{d}^{2}}\]                                   

    B)  \[3{{d}^{5}}\]

    C)  \[3{{d}^{7}}\]                                   

    D)  \[3{{d}^{9}}\]

    Correct Answer: B

    Solution :

                    Magnetic moment\[=\sqrt{n(n+2)}BM\]where\[n\]is the number of unpaired electrons. Maximum the value of unpaired electron, greater the value of magnetic moment. So,\[3{{d}^{5}}\]has highest value of magnetic moment.
