The magnetic moment of metal ion of first transition series is `2.83 B

1.	The magnetic moment of metal ion of first transition series is `2.83 BM`. Therefore, it will have unpaied electronsA. 2B. 4C. 3D. 6
Answer» Correct Answer - A `mu = sqrt(n (n + 2)) (mu =` magnitic moment) `(n =` no. of unparied electrons.). `2.8 = sqrt(n (n + 2))` `n (n + 2) = 8` `n^(2) + 2n - 8 = 0` `n = + 2`.
