Educational kit: Structure and properties of substances
Set “Structure and properties of substances”: 17 items with a large model of molecules and electron clouds, 6 experiments on the relationship between structure and properties.
A set for studying the structure of matter at the atomic-molecular level: electron shells, chemical bonds, crystalline and molecular structures, patterns of changes in the properties of elements in the periodic table. Includes 17 equipment items and 6 experiments: extraction of iodine from kelp, growing copper sulfate crystals, experimental verification of the polarity of molecules, preparation and use of complex compounds, analysis and prediction of the properties of materials through electronegativity. The centrepiece is a model of molecules and electron clouds (296 atoms, 338 bonds, orbitals and electron clouds); it is complemented by a porcelain spotting plate for microscale reactions, graduated test tubes, a crucible with a lid and laboratory beakers.
