outer electronic configration of Fe is : 3d- 6 electrons , 4s- 2 electrons.

outer electronic configration of Fe3+ is : 3d- 5 electrons

so there is loss of 3 electrons when Fe ionises to form Fe3+

3+ means that the ion has won 3 positive charges and so lost 3 electrons

If you're asking what happens from Fe(s) ==> Fe+3 + 3e-

The answer is it loses 3 electrons (oxidizes)
