... bond is greater than the average of the two atomic orbital ionisation energies . This is nearly always the case . Now we look empirically at the connection between these ( -8e " ) values and the bond energies , leaving the formal theory ...

... bond form- ation . Providing the bond is not too polar , the important factor in determining the bond energy is the ionisation energy terms ( -de " ) and since this is sensitive to the electro- negativities of the atomic orbitals forming ...
