Ammonia 3D Molecular Model — CAS 7664-41-7

Ammonia (H3N, CAS 7664-41-7) — a free educational 3D molecular model for teachers and students, by MolGod.org. Read the atoms directly: each sphere bears an engraved element symbol.

Lay Ammonia on the desk and search for a ring: there isn't one. Its 4 atoms hang together through 3 bonds (all of them single). A five-minute warm-up: read the symbol on every sphere and write down the totals (3 H + 1 N = 4 atoms). When you discuss intermolecular forces, note 1 hydrogen-bond donor and 1 acceptor (computed).

Teachers and students can use this MolGod.org model free of charge. Teachers: give each table a model and have students write the formula from the engraved atoms.

A ball-and-stick model of Ammonia with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 38,454 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.

Names in other languages: Ammoniak (de); ammoniac (fr); ammoniaca (it); ammoniak (nl); amoniak (pl); 氨 (zh).
