Compact-exploded molecular models 103 atoms

This comprehensive set is intended for the teacher.
It allows to build a large number of molecules in their compact and expanded representation and to illustrate all the subjects mentioned in middle school and high school programs.
It is possible to study:
- simple molecules (O₂, H₂, H₂O, NH₃, CO₂, ...),
- VSEPR on simple molecules CH₄, NH₃ and H₂O with visualization of non-bonding pairs,
- stereochemistry and common functions of organic chemistry,
- polymers (PVC, polystyrene...), natural macromolecules (peptides, oligosaccharides...),
The set comes with instructions in a plastic case.
