Why is oxygen paramagnetic

Both bond length and bond energy changes as the bond order increases and as the number of electrons shared between two atoms in a molecule increases, the bond order of a bond increases, the strength of the bond increases and the distance between nuclei decreases Table 9.

The above trend can be observed in the first row diatomics in Figure 9. The bond order can be determined directly form the molecular orbital electron configurations. For diatomics, the occupations can correlate to bond length, bond energies Figure 9. The bond length in the oxygen species can be explained by the positions of the electrons in molecular orbital theory. This leads to a predicted bond order of. The bond order is determined from the the electron configurations.

The electron configurations for the four species are contrasted below. Sign up to join this community. The best answers are voted up and rise to the top.

I don't think that Lewis structures are going to help you here because they hold no information about the spin of electrons. But note the plural. What if you have two unpaired electrons and your molecule is a biradical? SE explaining why O2 is paramagnetic? Everything I can find uses it as an example, but there's nothing explaining it Edit: chemistry.
