Express your answer numerically as an integer. Our expert help has broken down your problem into an easy-to-learn solution you can count on. Iron (Fe) is a transition metal that follows the Aufbau rule of the filling of atomic orbitals. of Fe3+ we have to subtract 3 electrons from the outermost shell which is 4s and 3d orbitals. giving a charge of +2 A half filled 3d orbital is somewhat stable so the 6 3d electrons are not stable. The easiest way to create electron configurations is using an electron configuration table, which is a way of writing down the various orbitals available to electrons. xs kf qx no sx un uk bm lb jv
