Wall board: Periodic table of elements with accessories for building chemical structures and atoms according to Bohr

MACHINE TRANSLATION (not authorised yet)

A large, colorful periodic table of chemical elements, 160 cm x 92 cm in size, in the form of a foil board framed with poles and a string for hanging on the wall. It presents the following information about the elements: chemical symbol, name and atomic number, degree of oxidation, atomic mass, electronic configuration, as well as the nature of the oxide, melting and boiling point, ionization value, density and electronegativity. The board is very clear and legible, so that it is visible from the last bench in the class. Additional accessories included: The magnetic teaching kit for the creation and modeling of atoms and molecules based on the Bohr model of the atom is an excellent educational tool for the teacher. Step-by-step modeling of selected elements and molecules on a magnetic school board makes it possible to explain the structure of atoms, as well as link their structure to the periodic table of elements, thanks to the attached elements of this system. This allows you to model an atom according to the information read sequentially from the cell of the periodic table on the table (to choose from H, O, Ar - hydrogen, oxygen, argon) with basic information about the group, period, atomic number, mass number of a given element (apart from its symbol and name). Different colors of atomic nuclei and frames for marking the valence electrons of the connecting elements, as well as the determination of ionic values ​​in the case of modeling ionic bonds help in this. Educational kit for building chemical structures in the field of organic and inorganic chemistry. It consists of spheres with holes symbolizing atoms and elements and connectors symbolizing bonds. The set includes 75 models of atoms-elements and 30 connectors. All elements are placed in a plastic closed box.
