Molecule black outline icon
Outline molecule model with a central atom bonded to five circles of different sizes
About the Molecule black outline icon
A ball-and-stick molecular model: one large central sphere with five tapered bonds radiating outward to smaller and larger atoms, one of them oversized at the lower right, giving the cluster an off-balance, three-dimensional feel. It signals chemistry, molecular biology, research and formulation, so it suits lab and pharma websites, science education apps, skincare ingredient pages, biotech decks and R&D dashboards.
Bonds taper from wide to narrow to suggest depth, and the varied circle sizes keep the silhouette from reading as a plain network graph. Keep it at 32 px or larger so the smallest atom stays visible; it pairs with flask, DNA and microscope icons.
This is the black outline version of the molecule 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.
