✏️ Lewis structure & formal charge workstation

Build representative Lewis structures, count valence electrons and inspect formal charges and resonance.

FC = valence − nonbonding − ½(bonding electrons)

🧠 Best Lewis contributors

Useful structures generally minimise formal-charge separation while respecting octets where appropriate and placing negative charge on more electronegative atoms when possible.

Safety: This is a bonding model.

Model limitation: Lewis structures are electron-counting models; resonance structures are not rapidly interconverting molecules but contributors to one delocalised structure.
