Question

Which ion has the highest value of theoretical magnetic moment?

विकल्प

• Cr³⁺

• Co³⁺

• Ti³⁺

• V³⁺

Answer 1

Co³⁺

Explanation:

Magnetic moment = `sqrt("n"("n" + 2))` BM

(where n = number of unpaired electrons)

As a result, the quantity of unpaired electrons has a direct relationship with a magnetic moment.

Ion	Outer electronic conftguratlon	No. of unpaired electrons	Calculated value of magnetic moment
Cr3+	3d3	3	3.87 BM
Co3+	3d6	4	4.90 BM
Ti3+	3d1	1	1.73 BM
V3+	3d2	2	2.83 BM
