Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFExplanation:
The magnetic moment of a divalent ion in an aqueous solution depends on its electronic configuration, which in turn is determined by the element's atomic number.
Atomic number (z = 25) belongs to Mn atom
E.C. of Mn = [Ar]3d54s2
E.C. of Mn2+ ion = [Ar]3d54s0
\(μ=\sqrt{n(n+2)} B M\)
Number of unpaired electrons = 5
\(μ=\sqrt{5(5+2)}=\sqrt{35} \mathrm{BM}\)
μ = 5.92 BM
