Answer:

=>$<marque> configuration of Fe⁺ cation is:</p><p></p><p>1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁶ 4s¹</p><p></p><p>and of Fe²⁺ cation is:</p><p></p><p>1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁶</p><p></p><p>Sadly many people erroneously remove 3d electrons before 4s, believing that this level is more energetic. Such assumption is wrong, the 3d>4s orbital energy order holds only up to the calcium; for scandium and later elements, the correct orbital energy order is 3d<4s.$
