The atom visualizer is a multi-platform study aid application that allows students to visualize the atomic structure of any element on the periodic table.  The visualization includes atomic weights, numbers of protons, neutrons, electrons, as well as the element’s electron shell occupancy configuration (long hand as well as noble relative).  The atom visualizer currently supports all web-based and mobile platforms (where the user’s browser\mobile browser supports WebGL) as well as the Microsoft HoloLens mixed reality headset.
