Particle icon: a large center circle connected by four straight bonds to four smaller circles
About the Particle black filled icon
A central open circle sits at the middle of this mark, joined by four straight bonds to smaller circles set above, below, left and right. It reads instantly as a particle, atom or simple molecule, communicating science, structure and connection. Use it for chemistry course pages, physics app menus, laboratory dashboards, research report slides and nanotech product sites.
Strokes are even weight throughout, with the hub circle roughly three times the diameter of the satellite nodes so hierarchy stays clear at small sizes. It sits beside flask, microscope and DNA marks in the science set. Below 24 px, thicken the bonds slightly to stop them fading.
This is the solid black filled version of the particle 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.
