A perfect hands-on illustration of atoms, ions, isotopes, and more from the award-winning Bright of Sweden. This kit enables students to develop understanding of atomic structure with this tactile model of Bohr's atomic model. Students manipulate plastic electrons and protons on the model's clearly outlined electron shells to make an atom, learning how particles are divided inside the atom. The double-sided model features an electron shell on each side, so students can construct two atoms at a time and visualise how ions are formed. Contents:. 30 protons. 30 neutrons. 30 electrons. Supplied in a box, with lid. Can be easily stacked for smart storage. Size: 9" Diameter. Includes Lesson Plan.
