Which one of the following transition metals ions shows magnetic moment of 5.92 BM
Options
(a) Mn²⁺
(b) Ti³⁺
(c) Cr³⁺
(d) Cu²⁺
Correct Answer:
Mn²⁺
Explanation:
Magnetic moment = √n(n+2) = 5.92. i.e., n = 5 . Number of unpaired electron in Mn²⁺ = 5. Number of unpaired electron in Ti³⁺ = 1. Number of unpaired electron in Cr³⁺ = 3. Number of unpaired electron in Cu²⁺ = 1. Number of unpaired electrons in Co²⁺ = 3. Thus Mn²⁺ have magnetic moment = 5.92 BM.
