About the Physics Atom Orbits black outline icon
A small circle forms the nucleus at the center while three long ellipses cross over it at even angles, tracing electron paths around the core. It is the standard emblem for atomic science and research, fitting physics and chemistry course modules, lab and R&D section headers, school textbook and worksheet layouts, science museum wayfinding, and technology decks about innovation or nuclear energy.
The three orbits are equal in size and rotated in thirds, giving a balanced star-like symmetry with the nucleus left unfilled so it stays visible where the rings overlap. It works next to microscope, flask and DNA icons. At 16px, thicken the strokes slightly so the crossings do not fill in.
This is the black outline version of the physics atom orbits icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
