Chemistry learning resources
Explore atoms, molecules and chemical phenomena using interactive models and simulations. Connect microscopic structures with observable changes.
← All subjects and topics
Chemistry models help visualize structures that are difficult to observe directly. Explore particles, atoms and changes in matter through the public resources below.
Ideas for learning: Identify what a model represents and what it simplifies. Use simulations for discussion; they do not replace safety guidance for real laboratory experiments.
