Abstract: The present invention provides an interactive atomic model that comprises a compartment (201) that is enclosed by walls and a lid (100) that can be opened, and at least two elementary particle models (301, 302, 303) which are contained in the compartment (201). The lid (100) has an atomic model surface (101) that defines a centre area (103) and a number of closed orbits (102), whereby said centre area (103) defines resting positions that are well defined in space for at least one of said elementary particle models (301, 302, 303) and said closed orbits (102) defines resting positions that are well defined along the respective closed orbit or at least one of said elementary particle models (301, 302, 303). The interactive atomic model thereby enables simple and effective understanding for the constitution of atoms.
