Basic kit for organic and inorganic chemistry

The set contains 92 elements made from colored plastic (in the previous version: 86 elements) enabling the construction of a wide range of chemical structures. The set includes models (52 pieces) of elements such as carbon, hydrogen, boron, nitrogen, oxygen, sulfur, phosphorus, halogens and metals. Each element is represented by 1-6 types of models; for example, phosphorus is represented by three ball models with 5 and 3 openings and angles of 90°, 120°, and 107°. Metals are represented by six models and can symbolize, among others: Cl, F, Na, Ca, Mg, Be, Al, Si, Cu. The bonds (including single covalent, double, triple, ionic, as well as complex and hydrogen bonds - e.g., in the copper ion or ice) are represented by three types of connectors. Additional elements are models of elements with the sp3, dsp3, d2sp3 structure (3 pieces) and 3 pear-shaped leaflets representing lone pairs of electrons (electron cloud). From the elements of the set you can build large and clear structures – they are correct and well-defined.

The set enables constructing simple organic molecules (with various functional groups) and inorganic ones, including: C₂H₂ (ethyne), CH₃CH₂OH (ethanol), CH₃COOH (acetic acid), CH₃COOCH₃ (ethyl acetate), CH₃CHO (acetone), CH₂OHCH₂OH (ethylene glycol), CH₂NH₂COOH (glycine), C₆H₁₂ (cyclohexane), H₂SO₄ (sulfuric acid), HClO₄ (thunder acid), H₃PO₄ (orthophosphoric acid), H₂CO₃ (carbonic acid), HCl (hydrochloric acid).
