Question

The highest magnetic moment shown by the transition metal ion with the outermost electronic configuration is: 

(a) 3d⁵ 

(b) 3d² 

(c) 3d⁷ 

(d) 3d⁹

Answer 1

Correct Answer is: (a) 3d⁵ 

The highest magnetic moment is shown by the transition metal ion with outer electronic configuration d⁵ as it has maximum (five) number of unpaired electrons. Higher is the number of unpaired electrons, higher is the magnetic moment.
