Build Molecules

Build Molecules – Interactive Chemistry Learning App

Discover chemistry by building real molecules! 🧪

Build Molecules is an interactive molecule builder and chemistry learning game where you can create molecular structures, explore the periodic table, understand chemical bonding, and learn through quizzes, experiments, and scientific challenges. Experiment in your own virtual chemistry lab.

⚗️ INTERACTIVE MOLECULE BUILDER

Build molecules by dragging atoms into the workspace. Atoms form bonds automatically according to chemical valence rules, helping you understand how elements combine.

• Create single, double, and triple bonds.

• Explore valence and molecular structures.

• Check atom connections and identify recognized molecules.

🔬 DISCOVER 436 MOLECULES

Explore a library of 436 molecules, including water, oxygen, methane, benzene, alcohols, organic compounds, acids, and salts. Load molecules into the workspace, examine their structures, and access scientific information through PubChem links and explore a wide range of chemical compounds.

⚛️ LEARN LEWIS STRUCTURES

Visualize chemical bonds and lone electron pairs with interactive Lewis structures. Explore valence electrons, electron distribution, and how atoms bond.

🧬 EXPLORE THE PERIODIC TABLE

Discover all 118 chemical elements across 10 categories. Explore atomic number and weight, valence, electronegativity, atomic radius, electron configuration, density, melting and boiling points, ionic charge, and radioactive properties.

Switch between Simple View for quick atom selection and Detailed View to investigate element properties. Browse your collection and deepen your understanding of the periodic table.

☢️ DISCOVER 11 ISOTOPES

Explore Deuterium, Tritium, Carbon-13, Carbon-14, Potassium-40, Cobalt-60, Iodine-131, Cesium-137, Uranium-235, and Uranium-238. Learn about isotopes, radioactivity, and half-lives.

📚 CREATE YOUR CHEMISTRY NOTEBOOK

Study with 238 learning cards across 22 chemistry topics, from atomic structure and chemical bonding to organic chemistry, electrochemistry, and nuclear chemistry. Unlock My Notebook to create custom tabs, search for cards, and organize and reorder your materials. Build a personalized study guide.

🧪 TEST YOUR CHEMISTRY KNOWLEDGE

Challenge yourself with 416 questions across 104 quiz blocks. Practice chemistry concepts, review your answers, track your progress, and earn XP, atoms, and energy as you learn. Complete daily challenges and unlock new elements.

🏫 BUILD YOUR CHEMISTRY CAMPUS

Develop a scientific campus with 19 buildings, research projects, and energy facilities. Generate resources over time, recruit mentors, improve your laboratory, and expand your scientific capabilities.
