Question

A weak-field octahedral 3d metal ion has the configuration t 2 g ​ x e g ​ ², where x can take any value allowed for a 3d ion. The ratio of the spin-only magnetic moment for the minimum possible x to that for the maximum possible x is closest to

TestHub · Accepted Answer

With two electrons in e g ​ , x runs from 3 (d⁵, Fe³⁺ or Mn²⁺) to 6 (d⁸, Ni²⁺). Minimum x = 3 gives five unpaired electrons, μ = √35 = 5.92 BM. Maximum x = 6 gives two unpaired electrons, μ = √8 = 2.83 BM. Ratio = 5.92/2.83 = 2.09, closest to 2.1.
