Question

The magnetic moment of a particular ion is 2 √6 B.M. The
ion is
(a) Mn²⁺ (b) Fe³⁺
(c) Co²⁺ (d) Co³⁺

Answer 1

The ion is Co³⁺.

Option (D) is correct.

Explanation:

We are given that:

The magnetic moment of a particular ion =  2√6 B.M

solution:

The electronic configuration of Co3+ is given by:

Co3+ ---> 1s2 2s2, 2p6, 3s2, 3p6, 4s0, 3d6

Now the spin of electrons in each orbital can be shown as:

⇵ ↑ ↑ ↑ ↑

We can see the number pf unpaired electrons "n" = 4

So

Magnetic moment "μ" = √4 ( 4+ 2)

μ = √ 24 B.M

Thus the ion is Co³⁺.
