8.4 Molecular Orbital Theory – Chemistry

The order of a covalent bond is a guide to its strength; a bond between two given atoms becomes stronger as the bond order increases (Table 1 in Chapter 8.1 Valence Bond Theory). If the distribution of electrons in the molecular orbitals between two atoms is such that the resulting bond would have a bond order of zero, a stable bond does not form.

In order to have a complete, balanced redox system, there must be at least one reduction and one oxidation; one cannot occur without the other and they will occur simultaneously. For a balanced system, the nuer of electrons lost in the oxidation reaction must be equal to the nuer of electrons gained in the reduction step.
