The magnetic moment of a transition metal having 3 unpaired electrons is 3.87 BM.
Given:
Transition metal having 3 unpaired electrons.
To Find:
The magnetic moment.
Solution:
To find the magnetic moment of a transition metal having 3 unpaired electrons we will follow the following steps:
Transition metals are d-block elements that have incompletely filled d-orbitals. These d-orbitals may have unpaired electrons or paired electrons depending upon the group and the ligands attached.
If they have unpaired electrons then they are known as paramagnetic and they show attraction in an applied magnetic field. Similarly, if all the electrons are paired then they show diamagnetism and show repulsion in applied magnetic filled.
As we know,
An unpaired electron's magnetic moment can be calculated by the formula:
Answers & Comments

As we know,
An unpaired electron's magnetic moment can be calculated by the formula:
[tex] \sqrt{n(n + 2)} BM[/tex]
Here, n is a number of unpaired electrons.
Now,
Putting values to get the magnetic moment:
Magnetic moment =
[tex]\sqrt{3(3+ 2)} BM[/tex]
[tex] \sqrt{5 \times 3} BM = \sqrt{15} BM = 3.87 BM[/tex]
Henceforth, the magnetic moment of a transition metal having 3 unpaired electrons is 3.87 BM.
