Make certain each sentence is complete before submitting your answer. Reset Help farther The 4s valence electrons in Fe are on average from the nucleus than the 3d closer electrons, so Fe is larger than Fe2+. one orbital Because there are five 3d orbitals, in Fe2+ at least must contain a pair of electrons. two orbitals five orbitals Removing one electron to form Fe3+ significantly repulsion, increasing the nuclear charge experienced by each of the other d electrons and decreasing the size of the ion. reduces increases
