The spin-only magnetic moment value of

Question:

The spin-only magnetic moment value of $\mathrm{B}_{2}^{+}$ species is $\times 10^{-2} \mathrm{BM}$. (Nearest integer)

[Given : $\sqrt{3}=1.73$ ]

Solution:

$\mathrm{B}_{2}^{+} \Rightarrow \sigma_{1 \mathrm{~s}}^{2} \sigma_{1 \mathrm{~s}}^{* 2} \sigma_{2 \mathrm{~s}}^{2} \sigma_{2 \mathrm{~s}}^{* 2} \pi_{2 p y}^{1} \simeq \pi_{2 p z}^{0}$

$\Rightarrow 9 \mathrm{e}^{-}$

$\mu=\sqrt{1(1+2)}=\sqrt{3} \mathrm{BM}$

$=1.73 \mathrm{BM}$

$=1.73 \times 10^{-2} \mathrm{BM}$
