About the Atom black outline icon
This design shows a single round nucleus at the center, ringed by three long elliptical orbital paths that cross each other at even angles to form a symmetrical star-like frame. It communicates atomic structure, scientific research, energy and experimentation. Use it for chemistry and physics course pages, lab and research websites, science app navigation, nuclear energy dashboards, and school presentation slides about matter and particles.
The composition is built from three identical ellipses rotated 60 degrees apart around a small open circle, giving a balanced radial shape that reads clearly even at small sizes. It pairs naturally with microscope, flask, DNA and molecule icons in the library. Because the orbit strokes are thin and overlap, keep it at 24px or larger so the crossings stay legible.
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.
