###### FREE Expert Solution

We are asked to determine the number of d electrons in the metal ion.

To do so, we shall use the formula below:

[Fe(CN)6]3-

The charge of Fe (denote as x)  in the complex is:

x + 6 (-1)  = -3

x - 6 = -3

+6       +6

x = + 3

Fe is in Group 8 and has a charge of +3, therefore the number of d electrons is:

number of d electrons = 8 - (+3) = 5
