Answer 1

Answer:

1.73 B.M.

Explanation:

electronic configuration of Ti(3+) = d1

=> unpaired electrons, n = 1

=> spin only magnetic moment = √(n×(n+2)) = √(1(1+2)) = √3 = 1.73 B.M.

so correct option is A. 1.73 B.M.

Answer 2

Given,

The Ti⁺³ ion is given.

To find,

We have to find the spin-only magnetic moment for Ti⁺³ ion.

Solution,

The spin-only magnetic moment for Ti⁺³ ion is 1.73 B.M.

We can simply find the spin-only magnetic moment for Ti⁺³ ion by using the formula,

    μ = √n(n+2)

Electronic configuration of Ti⁺³ ion is

   Ti⁺³ = 3d¹

This implies that there is only 1 unpaired electron in Ti⁺³ ion.

    μ = √1(1+2)

    μ = √3

    μ = 1.73 B.M.

Hence, the spin-only magnetic moment for Ti⁺³ ion is 1.73 B.M.
