About the Particle black outline icon
A single circle sits at the center of this particle mark, with four straight bonds radiating out to smaller open rings placed at uneven angles. The layout reads as an atom, a molecule or a connected node cluster, which suits science and physics sections, chemistry lesson slides, nanotechnology product pages, research dashboards and energy or materials branding.
Line weight stays even across the nucleus and its four arms, so the small rings stay legible when scaled down. The asymmetric spread keeps it from looking like a rigid molecular diagram and pairs well with microscope, DNA and flask icons. Keep it at 24px or larger.
This is the black outline version of the particle icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
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.
