Description of this simulation

Water (H2O): Formal-charge inspector — 0 on every atom. Two lone pairs compress the H–O–H angle and leave a strong net dipole.

What this model shows — and what it simplifies

Educational Model

Formal charge assigns bonding electrons equally between bonded atoms and compares that share with the neutral atom’s valence count.

Where do we see this in real life?

Chemists compare formal charges to choose the most useful Lewis structure and predict which atom a reagent will attack.
