Compact-exploded molecular models 61 atoms

This kit, designed for high school students, allows for the creation of molecules in compact and expanded representations. It is possible to cover high school curriculum. Illustration of the atomic structure of small molecules. Study of the geometry of molecules CH₄, NH₃, H₂O based on the repulsion of bonding and non-bonding electron pairs (VSEPR). Recognition of different families of compounds (carboxylic acids, ketones, aldehydes, alcohols, halogenated compounds, amines...). Rotational bonding: study of stereochemistry (free rotation of single bonds, Z and E isomerism...). Compatible with complex molecular model of organic chemistry and biochemistry. Possibility to represent the non-bonding orbitals of oxygen and nitrogen. Kit delivered in a box with instructions and a tool for breaking bonds.
