Trimethyl(4-vinylphenyl)silane (C11H16Si, CAS 1009-43-4) — a free educational 3D molecular model for teachers and students, by MolGod.org. Read the atoms directly: each sphere bears an engraved element symbol.
Start with the ring system: Trimethyl(4-vinylphenyl)silane has one aromatic 6-membered ring; in total the model carries 28 bonds (21 single, 1 double and 6 aromatic, drawn in Kekulé form). Hand the model round and let students tally the engraved atoms: 11 C + 16 H + 1 Si, 28 in total. Ask the class to locate the carbon-carbon double bond (C=C) and name each one. It makes aromaticity and delocalised electrons easier to see. Pair it with 4-Chlorostyrene (CAS 24991-47-7) and styrene (CAS 100-42-5) from the same collection to compare closely related structures.
Part of the MolGod.org free library of engraved molecules for chemistry classrooms. Teachers: let students set the model beside a skeletal formula and list what the drawing omits.

A ball-and-stick model of Trimethyl(4-vinylphenyl)silane 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: 342,940 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
