The highest magnetic moment is shown by the transition metal ion with which of the following outermost electronic configuration?

A$$3d^{2}$$
B$$3d^{5}$$
Correct Answer
C$$3d^{7}$$
D$$3d^{9}$$

Solution

As magnetic moment is $$\sqrt{n(n+2)}$$ where n is no. of unpair electron, so greater the no. of unpair electron and greater will be the magnetic moment of a ion. $$3d^2$$ has 2 unpair electron, $$3d^5$$ has 5 unpair electron, $$3d^7$$ has 3 unpair electron and $$3d^9$$ has 1 unpair electron. So, $$3d^5$$ has highest magnetic moment.
