$\text{Fe }:3{\text{d}}^{6}4{\text{s}}^2$

${\mathrm{Fe}}^{3+}: 3{\mathrm{d}}^{5}4{\mathrm{s}}^{\mathrm{o}}$

$\boxed{\uparrow }\boxed{\uparrow }\boxed{\uparrow }\boxed{\uparrow }\boxed{\uparrow }$

$\mathrm{n}=5$

The formula of magnetic moment $\left(\text{µ}\right)$ :

$\sqrt{\mathrm{n} \left(\mathrm{n}+2\right)} \mathrm{BM}$

Whereas:- $\text{n} =$ Number of unpaired electron

$\text{BM}=$ Bohr Magneton

$\text{µ}=\sqrt{35} \text{BM}$

$=5.92 \text{BM}$
