About the Atom black outline icon
Three elongated elliptical orbits cross each other at even angles, one lying flat and two tilted, with a small circle riding on three of the orbit paths as electrons. The nucleus is left open, so the structure reads as pure atomic motion and scientific energy. Use it for physics and chemistry course pages, laboratory and research branding, science-museum signage, nuclear-energy reports and developer tooling that borrows the atom as a framework mark.
The ellipses are long and narrow, which gives the symbol a wide, dynamic footprint rather than a compact ball, and the three electrons sit at different points so the orbits appear in motion. It pairs with molecule, flask, microscope and DNA icons. Keep it at 24px or larger so the crossing strokes stay separate.
This is the black outline version of the atom icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
