question_answer 54)

    The magnetic, nature of elements depends on the presence of unpaired electrons. Identify the configuration of transition element, .which shows highest magnetic moment. (a) 3d7                                   (b) 3d5            (c) 3d8                                   (d) 3d2

Answer:

                          (b) Greater the number of unpaired electron, higher will be its value of magnetic moment. Since, 3d5 has 5 unpaired electrons hence highest magnetic moment. = 5.95 BM
