Build Molecules

Discover chemistry by building real molecules.

Build Molecules is an interactive chemistry lab and chemistry game where students, teachers and science enthusiasts can experiment with atoms, create compounds and learn chemical structures in a visual and intuitive way.

INTERACTIVE MOLECULE BUILDER

Create molecules by dragging atoms into the workspace.

Atoms automatically form bonds when they are close enough, following real chemical valence rules.

The system analyzes your structure and identifies the molecule instantly.
