2 molecules built by the community
How it works:
1. Tap elements (H, O, C, N) to add atoms
2. Tap COMPLETE to check your molecule
3. If it matches a known compound, you earn a discovery
4. Each discovery teaches you real chemistry
Try first: Tap H, then O, then H — and complete it. You will discover water.
