Picked / Everything: atoms become spheres, bonds become sticks. As prosthetic: the bond graph becomes a blueprint: elements become bodies (C round box, N cylinder, O sphere, S torus, Cl cone), H becomes spikes, bond order sets how hard the join is, lone pairs are carved out, partial charge picks the material.

Polymer

units8

The picked molecule is the monomer. Each new unit joins the chain end, and one hydrogen leaves at every joint (condensation). Methane grows a polyethylene-like backbone.

Crystal

lattice

Anneal cools from the current temperature to 20 K over 24 s. With a lattice, each molecule is drawn to the nearest free site as it cools; without one, hydrogen bonds alone decide.

container

Heat shakes atoms and breaks weak bonds first (O–O at 146 kJ/mol goes long before C≡O at 1072). Polarity scales the partial charges; stickiness the London attraction.

Elements

el	valence	cov Å	vdW Å	χ

Pick an element (H C N O S L keys) and click in space or on an atom to add it. Bonds form where free valences meet; angles follow VSEPR: 180°, 120°, 109.5°, minus 2.5° per lone pair.
