Purpose
The project provides quick visual references and structured learning material for common molecules and ions. It is designed to supplement textbooks, class notes and instructor guidance—not replace them.
The generator
Detailed results come from a curated local JavaScript database and browser renderer. Unsupported inputs may use PubChem as a clearly labeled conventional 2D reference.
The educational library
Molecule guides and topic pages explain electron counting, bonding, formal charges, resonance, ions, organic connectivity and VSEPR geometry.
Editorial principles
- State what the tool actually supports.
- Clearly distinguish local Lewis results from PubChem fallback images.
- Do not publish ratings, user counts, accuracy percentages or institutional endorsements without verifiable evidence.
- Explain important limitations close to the generator output.
- Create compound-specific pages only when they add unique educational value.
- Separate educational explanations from promotional claims.
Accuracy and corrections
Lewis representations can depend on charge state, resonance convention, protonation, isomer, expanded-valence models and course expectations. Important results should be independently checked.
Corrections are welcomed through the contact page. Include the formula, displayed result, expected correction and supporting explanation.
