What is spin only magnetic moment of an element having one unpaired electron?
What is spin only magnetic moment of an element having one unpaired electron?
$0.34 \mathrm{BM}$
$1.0 \mathrm{BM}$
$1.73 \mathrm{BM}$
$3.1 \mathrm{BM}$
Solution
Spin only magnetic moment
$\begin{aligned}
& \mu=\sqrt{\mathrm{n}(\mathrm{n}+2)} \\
& \mathrm{n}=\text { number of unpaired electrons } \\
& \mathrm{n}=1 \\
& \mu=\sqrt{1+2}=\sqrt{3}=1.73 \mathrm{BM}
\end{aligned}$
