Atoms Never Vanish

⚛️ What does H₂O actually mean? It means 2 hydrogen atoms and 1 oxygen atom come together! By dragging atoms to build water, carbon dioxide, methane, and ammonia, you'll easily grasp how subscripts show the count. ⚖️ Next come chemical equations! In a chemical reaction, atoms are never created or destroyed, so both sides of the arrow must match. Adjust the coefficients until the table turns green. Balancing methane combustion takes three elements at once, while rusting iron needs 4, 3, and 2. 🧪 Finally, a cool rule: water always forms with 2 hydrogen for every 1 oxygen. Extra atoms without a match just stay left over! Built with code · Remix it to add your own equations!
About this app
Atoms Never Vanish is an interactive educational web app designed to introduce middle school chemistry concepts like molecular formulas, conservation of mass, and reaction stoichiometry. Users assemble molecules atom by atom, balance coefficients in chemical equations, and experiment with reactant ratios to see limiting reactants and leftovers in real time.
