Answer 1

Answer:

So Option ( 4 ) Ni⁺² , Zn⁺²  is the correct answer

Explanation:

Spin Magnetic Moment = √ n ( n + 2 )

n = Number of unpaired electron

So

Option ( 1 )

Co⁺³

n = 4

Fe⁺²

n = 4

Option ( 2 )

Mn⁺²

n = 5

Fe⁺³

n = 5

Option ( 3 )

Cr⁺³

n = 3

V⁺²

n = 3

Option ( 4 )

Ni⁺²

n = 2

Zn⁺²

n = 0

As Option ( 4 ) Ni⁺² and Zn⁺² have different number of unpaired electrons so they will have different Spin Magnetic Moment

So Option ( 4 ) Ni⁺² , Zn⁺²  is the correct answer

Answer 2

Answer:

$n = 4$

$n = 5$

Explanation:

$\geqslant n = 3$

$n = 2$
