Although more complex these diagrams reveal a more realistic case for bonding allowing electrons to travel about a molecule rather than in between one. Web 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. This model contains both dotted lines that represent the areas that are pointed away from the view and solid lines that represent the areas that point towards the viewer.

The first major step is understanding the difference between two major theories. Web Molecular orbital diagrams are complex involving two additional orbitals electronegativity atomic symmetries and atomic energies. Explain the source of electronic conductivity and ionic conductivity.

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. Web In addition the relative ordering of the orbital energies is the same for nearly all of the homonuclear diatomic molecules. Fill the molecular orbitals in the energy-level diagram beginning with the orbital with the lowest energy.
