Problem: In the ground-state electron configuration of Fe3+, how many unpaired electrons are present?When an atom forms an ion, it will gain or lose electrons to attain a more stable electron configuration, frequently that of a noble gas. Nonmetals tend to form anions by gaining electrons, which enter the lowest energy unoccupied orbital. Metals tend to form cations by losing electrons. Main group metals lose electrons in the reverse order of filling. Transition metals, however, lose s electrons first.
