Cool! Probably, you should add names for all pieces, it'll suit well for studying the Atom model. Also, maybe a short tutorial?

Thank you for downloading!
The manual provided in the game folder and in the download box provides descriptions of all the particles in AtomBox, as well as their physics interactions. It also shows how to use the simulation. I wanted to keep the application itself as free of text as possible so I put all the tutorial information in the provided manual.
You can also right-click on a spawned particle to get more information on it and change its kinetic energy and motion vector.
