Chemistry Lab Kits for Schools and Colleges ATICO Export Multi Function Set Magnetic

The Toytomics system was developed to make chemistry lessons more efficient.
The patented Toytomics teaching atom model shows for the first time all valence electrons, free electron pairs, plus and minus charges, electrostatic forces of ions and hydrogen bonds, coordination bonds and ionic bonds.
The Toytomics system makes it easy to teach abstract concepts of chemistry, such as chemical equations, electron line formulae, structures, bonds, forces and many other chemical concepts.
Pupils experience these complicated teaching concepts without difficulty by playing with the Toytomics atoms in class.
As almost all chemical reactions can be visualised with the Toytomics atoms, the models can be used in all year groups.
In contrast to the previous CLASSIC system, the Toytomics MAGNETIC system uses high-quality neodymium permanent magnets to demonstrate electrostatic forces such as hydrogen bonds or electrostatic attraction forces between free electron pairs and metal ions.

Application examples:

• All application examples of the basic set
• Atomic structure: single occupation rule (Hund rule), free electron pairs, periodic properties
• Octet rule: Full occupation of the shells
• Halogens: F2, Cl2, radical fission
• Radical halogen reactions: Substitution, elimination
• Radical addition: ethylene, acetylene or benzene, butadiene reactions
• Radical polymerisation: vinyl chloride
• Hydrogen acids: HCl, H2S, protolysis, ion formation, e.g. Cl-, F-, hydrogen sulphide
• Hydrogen bonds (halogens)
• Oxides of the 3rd period (non-metals): SO, SO2, SO3, CL2O, CL2O3, CL2O5, CL2O7, hydrolysis to the oxygen acids
• Oxygen acids of the 3rd period (non-metals): H3PO4, H2SO4, HCLO4, oxidation states, protolysis, ions, such as di-hydrogen phosphate, structures of acids, ions, zwitterions, octet extension
