Answer 2

Explanation:

To Find -

• $\mathsf{Magnetic \: Moment \: of \: [NiCl_{4}] {}^{2 - } }$

Solution :-

Calculation of O.N. :-

→ x - 1×4 = -2

→ x = 4 - 2

→ x = 2

Now,

Electronic configuration of Ni

• $\mathsf{[Ar] 4s {}^{2} 3d {}^{8} }$

Then,

$\mathsf{Electronic \: configuration \: of \: Ni {}^{2 + } }$

• $\mathsf{[Ar] 3d {}^{8} }$

Orbital diagram :-

( Refer to the attachment. )

Hence,

Number of unpaired electron are 2.

$\mathsf{Magnetic \: moment ( \mu)= \sqrt{n(n + 2)} B.M.}$

Here,

n = No. of unpaired electron

Then,

$\mathsf{ \mu = \sqrt{2(2 + 2)} B.M.}$

$\mathsf{ \mu = \sqrt{8} B.M.}$

Hence,

$\mathsf{ \mu = 2\sqrt{2} B.M.}$
