5-Amino-1,2-dihydro-3H-1,2,4-triazol-3-one (C2H4N4O, CAS 1003-35-6) — a free educational 3D molecular model for teachers and students, by MolGod.org. Symbols are engraved into every atom, so students read atoms by symbol, not by colour. In 5-Amino-1,2-dihydro-3H-1,2,4-triazol-3-one the ring system sets the overall shape: one 5-membered ring. Altogether 11 bonds hold the model together (9 single and 2 double). Hand the model round and let students tally the engraved atoms: 2 C + 4 H + 4 N + 1 O, 11 in total. It makes heteroaromatic rings (nitrogen inside an aromatic ring), as well as amines and basicity easier to see.
