Bohr Spatial Model Kit for Building Atoms

Bohr Spatial Model Kit for Building Atoms

A teaching kit for creating models of atoms, ions, and isotopes based on the Bohr model is a wonderful educational tool for students. It enables hands-on experiences with the smallest elementary particles.

Kit contents:

• a box with a lid, four electron shells in the lid and on the bottom of the box;
• 30 protons;
• 30 neutrons;
• 30 electrons.

Kit Capabilities

The kit enables building models of atoms, isotopes, and simple molecules according to Niels Bohr. In addition, it also allows illustrating the structure of isotopes – atoms with the same number of protons but differing in the number of neutrons in the nucleus.

With the kit you can also visualize the structure of an atom, the arrangement of electrons with respect to the nucleus on the individual electron shells K, L, M, N according to 2n^2 (electron configuration). The electrons placed on the outermost shell are called valence electrons, and they participate in chemical bonding.

Bohr demonstrated, among other things, that...

• an electron in an atom moves along a circular orbit under Coulomb attraction between the electron and the nucleus, and this motion obeys the laws of classical mechanics;
• instead of an infinite number of orbits allowed from the perspective of classical mechanics, the electron can move only along such orbits for which the angular momentum L is equal to an integer multiple of Planck's constant divided by 2π.
