CONSTRUCTION KIT OF MODELS OF ELECTRON SHELLS AND ATOMIC NUCLEI OF CHEMICAL ELEMENTS

摘要

FIELD: testing equipment.;SUBSTANCE: invention relates to training demonstration aids for interactive learning, and scientific and technical works using modelling in the atomic structures and intraatomic processes. The construction kit consists of two sets - electron and nuclear. The set designed for the physical representation, energy levels in the electron shells of an atom contains at least 120 light-weight balls, on the equator of which an electron is represented in the form of a ring with an arrow pointing the direction of rotation dividing the ball on the hemispheres painted like a bar magnet. The balls have holes for mounting on intersecting guiding axes of three stands. The stands rotate in a horizontal plane on supports, imitating the rotation of the atom. The second nuclear set of the construction kit of models contains at least three stands with two and three guiding axes. The first stand consists of three guiding axes mutually intersecting in the middle at right angle in one point. The second stand consists of two guiding axes mutually intersecting in the middle in one point, the vertical axis is straight, and the horizontal axis is S-shaped. The third fork stand consists of two vertical parallel axes rotating symmetrically around the vertical common axis of rotation on the horizontal support. All balls representing protons and neutrons are located in the nucleus model on the stand so that the total nuclear spin and parity correspond to the experimental data of nuclear physics.;EFFECT: modelling the spatial relationship of electrons, protons and neutrons in the atom.;50 dwg
