Sub-Topics

Sub-Topics. Lecture 7. Molecular Orbital Theory. Molecular Orbital Theory Orbital Overlap A bond can only be formed when two atomic orbitals of two atoms overlap Orbitals must be of similar energy To simplify the theory in our context, the 4s and 4p orbitals on the metal atom are ignored.
