Interactive Simulator · Inside the Atom

Hold the Electron in Orbit

Every atom has a tiny positive nucleus at its centre, with light negative electrons moving around it. The electrons are held by the pull of the positive nucleus, like the Moon held by Earth, but with electric force instead of gravity. Set the electron's speed so it settles into a steady orbit on the target ring. Too slow and the pull drags it in; too fast and it escapes.
