O2+ = 112 pm
O2 = 121 pm
O2- = 128 pm
O22- = 149 pm
In the table below, the bond orders are predicted from electron configurations by subtracting the number of electrons in bonding orbitals from the number of electrons in antibonding (*) orbitals, and dividing by two.
|Molecule||Electron configuration||Bond order||Bond length (pm)|
