WebO X 2 has a double bond in its normal form. That is O = O. There are no unpaired electrons in this case are there since there are 2 lone pairs on each oxygen. However 1 resonance structure would be O − O (result of homolytic cleavage of double bond) where each O is a free radical (a negatively charged one at that). WebOxygen, for example, has the electron configuration 1 s2 2 s2 2 p4, whereas the oxygen anion has the electron configuration of the noble gas neon (Ne), 1 s2 2 s2 2 p6. The two additional electrons required to fill the valence orbitals give the oxide ion the charge of 2– (O 2– ).
