Draw a structure and have every atom checked, solve one step by step, compare resonance contributors, and turn VSEPR shapes in 3D. Every answer comes with its reasoning: where each electron went, and why.
Live example: water
Lines are shared electron pairs, and the cyan dots are oxygen's lone pairs. Those lone pairs repel harder than the bonds, bending water to about 104.5 degrees.
Every tool draws on the same engine, so a compound's structure, formal charges and shape agree wherever you meet them, from a first octet to XeF₄.
No black boxes. Electron counts, central-atom choices, formal charges, and octet exceptions come with the reasoning, not just the result.
Formal charge is computed exactly as valence minus nonbonding minus half the bonding electrons, then validated so charges always sum to the molecular charge and the electrons always balance.
Classes, assignments, auto-grading with teacher overrides, and reports of the mistakes your class actually makes, problem by problem.
No installs and no textbook licenses. Type anything from H₂O to XeF₄ into the generator and read how its structure is built, step by step.
Two structures side-by-side: bonding, charges, molecular geometry.
