Question

Sort the following in decreasing order of their magnetic moments.

• A. $C{o}^{2+}$
• B. $F{e}^{2+}$
• C. $M{n}^{2+}$
• D. $T{i}^{3+}$

Answer 1

$M{n}^{2+}$ has 5 unpaired electrons,
Magnetic moment = 5.91 BM.
$F{e}^{2+}$ has 4 unpaired electrons,
Magnetic moment = 4.89 BM.
$C{o}^{2+}$ has 3 unpaired electrons,
Magnetic moment = 3.87 BM.
$T{i}^{3+}$ has 1 unpaired electrons,
Magnetic moment = 1.73 BM.
