Abstract: The Electron-Space Display Model (ESDM) is a teaching aid for demonstrating the systematic patterns in which electrons are distributed within space confinements, called shells and subshells, radiating outward in the space surrounding an atomic nucleus. Among the components of the ESDM is a diagram depicting, by means of color-coded configurations, the shells and subshells contrived by scientists to conceptualize the atomic domains of electrons and how they lawfully inhabit those domains. The diagram also features specific points (tiny apertures) designated "electron-spaces" within the subshells illustrating places where electrons would conceptually be found if "frozen" in position. Behind the diagram is a rotatable wheel with over 5000 tiny apertures precisely and systematically placed such that they align in 103 different patterns with the apertures in the diagram.
