About this app
Lewis Structures and Molecular Shape is an interactive chemistry learning app for exploring valence electrons, electron pairs, molecular geometry, bond angles, and bond polarity. Browse three sections to change atoms, bonding pairs, lone pairs, and atom combinations, then observe how the resulting Lewis dot arrangement, shape, angle, and bond type change. Guided missions use examples including water, ammonia, carbon dioxide, methane, and ionic bonding.
Use cases
- High school students studying introductory chemistry
- Teachers demonstrating VSEPR molecular shapes and bond angles
- Learners practicing valence electrons and bonding capacity
- Classroom activities comparing polar, nonpolar covalent, and ionic bonds
Features
- Interactive Lewis dot diagrams for hydrogen, carbon, nitrogen, oxygen, fluorine, and neon
- Adjustable bonding-pair and lone-pair controls with molecular shape and bond-angle feedback
- Molecular geometry examples including linear, trigonal planar, bent, tetrahedral, and trigonal pyramidal
- Electronegativity comparison between two selected atoms
- Guided missions with reset and next controls across three chemistry topics
