Chemistry Model Kit vs Molecule Geometry 3D

Use your smartphone and a Google Cardboard viewer to visualize the 3D shapes of molecules as predicted by the Valence Shell Electron Pair Repulsion (VSEPR) model. Click on the models to explore the 3D shapes and their corresponding 2D representations. This app was created to help you understand and remember the predicted electronic geometries, molecular geometries, and bond angles for molecules with up to 6 electron regions around a central atom. Immerse yourself, explore, and learn. This app was created and developed at Tennessee Tech University by chemistry instructor Janet Coonce and computer science student Evgeny Vasilyev, in collaboration with TTU’s iCUBE, with significant contributions from chemical engineering student Savannah Hall and graphic art student Brandon

Molecule Geometry turns VSEPR practice into an interactive study tool. Rotate built-in molecules in 3D, or build your own from geometry templates by changing the central atom, ligands, and bond order with instant visual feedback. Study mode adds Quiz, Compare, and Guided Solver so you can practice instead of only browsing. Measure bond angles, show or hide dipoles, lone pairs, and bond types, inspect Lewis structures and resonance forms, and tap atoms to see the element name and formal charge. Save custom builds to your library, search by formula or name, and switch the interface language when you study. Great for class review, homework, and building intuition for geometry, polarity, hybridization, and electron-domain arrangement.
