About this app
Elements and Compounds is an interactive middle-school chemistry learning app about atomic structure, pure substances, compounds, and molecules. Adjust the numbers of protons, neutrons, and electrons to build hydrogen, carbon, oxygen, and other elements, classify substances from their chemical formulas, and assemble molecules such as water, carbon dioxide, methane, and ammonia.
Use cases
- Middle-school students learning introductory chemistry
- Teachers demonstrating atomic structure and chemical formulas
- Learners practicing the difference between elements and compounds
- Students building molecule models from individual atoms
Features
- Interactive proton, neutron, and electron controls for building atoms
- Visual explanation that proton count identifies an element
- Classification activities for pure element substances and compounds
- Chemical formula practice using subscripts and atom counts
- Molecule-building activities for H₂O, CO₂, CH₄, NH₃, and other examples
- Mission-based lessons with feedback, reset, and next-step controls
