A three-dimensional (3D) atomic model is a teaching tool designed to illustrate the structure of an atom, the spatial arrangement of subatomic particles, and the structure of orbitals in physics and chemistry lessons. The model's 30 cm diameter ensures good visibility even in a larger classroom, making it suitable as a demonstration tool for teachers. The three-dimensional design helps students understand the principles of the microworld, which are difficult to imagine from a two-dimensional drawing or textbook. The tool allows you to explain the composition of the atomic nucleus (protons and neutrons) and the distribution of the electron shell (electrons and energy levels).
