Question

Which of the following ions will have spin-only magnetic moment equal to 1.73 BM?

Sc³⁺, Ti³⁺, Fe²⁺, Cu²⁺, Co²⁺

विकल्प

• Sc³⁺, Fe²⁺

• Ti³⁺, Cu²⁺

• Fe²⁺, Co²⁺

• Cu²⁺, Co²⁺

Answer 1

Ti³⁺, Cu²⁺

Explanation:

A single unpaired electron has a magnetic moment µ = 1.73 BM.

Ti³⁺ and Cu²⁺ ions have single unpaired electrons in their outer electronic configurations of 3d¹ and 3d⁹, respectively.
