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. When light flashes from light sets within the housing of the ESDM, from behind the wheel and diagram, it penetrates the aligned apertures, and these flashes appear in the electron-spaces of the diagram against the atomic background. Turning the wheel in three-degree increments shows the electron distribution pattern within shells and subshells for each of the 103 elements featured in a conventional Periodic Table of the Elements. These distribution patterns have been, for many years, presented in chart form with several rows and columns of numbers and atomic symbols.
