What does ⚛ mean?

⚛ draws an atom the way early 20th-century physics pictured it: electrons circling a nucleus on elliptical orbits, the Rutherford–Bohr model. Real atoms do not look like this, but the image became shorthand for science, physics and atomic energy. You will see it on science-fair posters, in chemistry notes and as an icon for “science” categories.

Common uses

  • Science and physics headings: ⚛ Physics club
  • Tech and science bios
  • Nuclear energy topics
