About this model

Ammonia (H3N, CAS 7664-41-7) — a free educational 3D molecular model for teachers and students, by MolGod.org. Whatever the filament colour, each atom reads clearly thanks to its engraved symbol. Follow the chain of Ammonia from end to end: 4 atoms, 3 bonds (all of them single) and no ring anywhere. Give each pair of students the model and a blank sheet: recording every engraved symbol should lead them to 3 H + 1 N, which is 4 atoms. Computed hydrogen-bonding profile: 1 donor against 1 acceptor, a starting point for talking about attraction between molecules. Free for education: MolGod.org publishes engraved molecular models for teachers, students and schools. Teachers: pair it with the MolGod.org record to connect the 3D shape with identifiers and data. Full record and more free models: L…
