Question

what is the value of spin only magnetic moment if Fe2+ ion​

Answer 1

hi frnd

Answer : The magnetic moment is 4.89 BM

Solution :

The electronic configuration of Fe with atomic number of 26 is,

The oxidation state of Fe is 2+.

The electronic configuration of with atomic number of 24 is,

The number of unpaired electrons in Fe = 4

Formula used for magnetic moment :

where,

= magnetic moment

n = number of unpaired electrons

Now put all the given values in the above formula, we get the magnetic moment.

Therefore, the magnetic moment is 4.89 BM
