Molecular Orbital Energy Diagram. A molecular orbital diagram or mo diagram is a qualitative descriptive tool explaining chemical bonding in molecules in terms of molecular orbital theory in general and the linear combination of atomic orbitals lcao method in particular. Atomic valence electrons shown in boxes on the left and right fill the lower energy molecular orbitals before the higher ones just as is the case for atomic orbitals.
This means that the σ 1 s molecular orbital has a lower energy than either of the hydrogen 1s atomic orbitals. Atomic valence electrons shown in boxes on the left and right fill the lower energy molecular orbitals before the higher ones just as is the case for atomic orbitals.
