    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 electrons, greater the value of magnetic moment. So, \[3{{d}^{5}}\]has highest value of magnetic moment.
