The electron orbital simulator (EOS) is a Unity program that serves as a visual aid for learning the structure of the atom. On the left is a 3D model of the atom selected in the periodic table.
Each tool has different behavior for the right mouse button: Drag: move the entire molecule (you can already use the left mouse button for this) Rectangle select: select atoms and bonds using a rectangular selection area. Lasso select: select atoms and bonds by drawing a freehand selection area.
Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
Carbon Atom. Open this page with such a device to experience AR. Scan this code to open the model on your device, then, tap on the AR icon.
View a scale model of a hydrogen atom.
In this video we'll look at the atomic structure and Bohr model for the Carbon atom (C). We’ll use a Bohr diagram to visually represent where the electrons are around the nucleus of the C...
