Chemistry - GENERAL CHEMISTRY Question with Solution | TestHub

The magnetic moment of the metal ion can be calculated using

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

$\mathrm{n}=$number of unpaired electrons.

$\mathrm{\mu }=4.90 \mathrm{BM}$

$4.90\mathrm{BM}=\sqrt{\left(\mathrm{n}\right)(\mathrm{n}+2)} \mathrm{BM}$

$24 = \left(\mathrm{n}\right) (\mathrm{n} + 2)$

$\mathrm{n} = 4$
