About the Atom black filled icon
This icon shows a central nucleus circle crossed by three elliptical orbit rings, each carrying a small electron dot, forming the classic atom symbol. It communicates science, physics, chemistry and energy. Use it in education platforms, science apps, chemistry blogs, lab branding and presentation slides on research topics.
The three orbits are evenly rotated around the shared nucleus for a balanced, symmetrical look, with consistent stroke weight throughout. It pairs well with molecule, DNA and chemistry-flask icons in the library. Tip: its simple symmetry keeps it legible even at favicon size.
This is the solid black filled version of the atom icon: a bold silhouette that reads clearly at 16-24 px and on dark or busy backgrounds, and prints well in one colour.
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.
