We do not cover Lewis diagrams in the module because our 2D and 3D representation for atoms include the same information but are superior: they do not omit information about the orbitals. Lewis structures discard critical information about orbital assignments and occupations.

If desired, it's quite straighforward to create Lewis structures from the bonding diagrams used in the module: simply draw bond pairs and lone pairs in numbers corresponding to the quantities of each in the bonding diagram.

Here are Lewis diagrams for OH and H₂O based on the bonding diagrams in Figures 19.4 and 19.5.:

Normally, one cannot draw a Lewis diagram for OH because the rules for Lewis diagrams rely on satisfying the octet rule, which simply doesn't apply to radicals.
