Question

A transition metal complex shows a spin only magnetic moment of 3.87 BM at room temperature. The number of unpaired electrons in the metal is:

Answer 1

The number of unpaired electrons in the transition metal is 3.

Explanation:

• This can easily be derived using the magnetic movement formula. This term is used in both physics and chemistry. It defines the interaction of a magnet or metal with its surroundings i.e. the field applied to it.

• The unit of the magnetic movement formula is BM. It stands for Bohr Magneton.  Its formula is $\sqrt{n(n+2)}$. Here n  represents the number of freely available electrons.

Answer 2

• The number of unpaired electrons in the transition metal is 3.
