Question

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

Answer 1

3d5 electronic configuration.
it contain a 5 unpaired electrons

Answer 2

Answer: The electronic configuration must be $d^5$

Explanation:

Magnetic moment of an ion is calculated to determine its behavior with the magnetic field.

Paramagnetism arises because of the unpaired electrons and when the electrons get paired up, the ion shows diamagnetism.

The equation used to determine magnetic moment is:

$\mu=\sqrt{n(n+2)$

where,

n = number of unpaired electrons.

Transition metals are known as d-block elements in which the valence electrons enter d-orbital and the maximum number of electrons that can be occupied in orbitals will be 10.

So, the maximum number of unpaired electrons for transition elements is 5.

Hence, the electronic configuration must be $d^5$

$\mu=\sqrt{5(5+2)}=\sqrt{35}$
