Question

Calculate magnetic moment of Ti³⁺ by using spin only formula. (Z of Ti = 22)

Answer 1

Ti (Z = 22)

Electronic configuration of Ti = [Ar] 3d² 4s²

For Ti³⁺, remove three electrons (first from 4s, then 3d):

Ti³⁺ = [Ar] 3d¹

Number of unpaired electrons (n) = 1

Using spin-only formula:

μ = `sqrt(n(n + 2))` BM

= `sqrt(1(1 + 2))` BM

= `sqrt 3` BM

= 1.73 BM
