Answer: the Iron has 5 unpaired electrons in Fe⁺3 state.Explanation:the Iron has atomic number 26 has the following electronic configuration in the neutral state. Fe = 1s2, 2s2, 2p⁶, 3s2, 3p⁶, 4s2, 3d⁶When the Iron loses three electrons to get to +3 to load with the following electron configuration. Fe⁺3 = 1s2, 2s2, 2p⁶, 3s2, 3p⁶, 3d⁵The five electrons in d-orbital are unpaired as, 3(dz)1, 3d(xz)1, 3d(yz)1, 3d(xy)1, 3(dx2-y2)1
