(iii) ${Fe}^{3 +} \to 1{s}^{2}2{s}^{2}2{p}^{6}3{s}^{2}3{p}^{6}4{s}^{0}3{d}^{5}$



$n = 5$

$\mu = \sqrt{5\left(5 + 2\right)}$ = \sqrt{35}B . M .

(iv) ${Ni}^{+ 2} \to 1{s}^{2}2{s}^{2}2{p}^{6}3{s}^{2}3{p}^{6}4{s}^{0}3{d}^{8}$



$n = 2$

$\mu = \sqrt{2\left(2 + 2\right)} = \sqrt{8}B . M .</p></blockquote>$
