Toytomics Periodic System 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 the electrostatic attraction of free electron pairs to metal ions

Application examples:

• All application examples of the Basic Set Magnetic 6677585
• All application examples of the Multi Function Set Magnetic 6677586
• Atomic structure - noble gas state: noble gases He, Ne and Ar
• Electron transfer: RedOx reactions, reaching the octet state, metal ions, non-metal ions
• Ionic state: ionic bonding, ionic lattice, salts, rocks
• Set up RedOx equations with stoichiometric equalisation, e.g. Na + Cl2, Mg + O2, Na + O2
• Electrolysis, e.g. NaCl
• Alkali reactions: Na in water to H2 and OH-, Mg combustion, MgO in water to base
• Solubility of salts: Hydrate shell of metal ions, coordination of six free electron pairs of six
• water molecules
• Solubility: Hydrate shell via hydrogen coordination
• Complex formation: Coordination of free electron pairs with metal ions
• Geometrically different coordinations, e.g. octahedral, tetrahedral, square planar, linear
