Organic · Stereochemistry & isomers: 16 3D models

Every element as an atom, orbitals and bonding, crystals, ions and complexes, real compounds from every field of chemistry, substances in their natural form, electrochemistry and lab experiments (real sizes atoms → lab bench). Each one is a ready-made 3D model you can turn, recolour and place in a figure — open BioDioRama and type its name in the Library search.
