Ammonia (H3N, CAS 7664-41-7) — a free educational 3D molecular model for teachers and students, by MolGod.org. Element symbols are cut into each atom sphere: a self-labelled teaching aid. Follow the chain of Ammonia from end to end: 4 atoms, 3 bonds (all of them single) and no ring anywhere. How many atoms can the class find? The engraved spheres give 3 H + 1 N, so the answer should be 4. Students can look on the model for the 1 donor and 1 acceptor of hydrogen bonds; both figures are computed.…
