Linear Molecular Structure black filled icon

About the Linear Molecular Structure black filled icon

Three circles sit on one horizontal axis: a large central atom joined by straight bond lines to two smaller atoms at either end, the classic linear geometry of molecules like carbon dioxide. The shape communicates chemical bonding, molecular models and scientific structure. Use it in chemistry courseware, laboratory and pharma websites, research report slides, science app navigation and educational diagrams.

Proportions do the explaining: the center circle is roughly twice the diameter of the end atoms, and the two bonds are equal in length so the 180-degree geometry reads instantly. Outlines keep the nodes open rather than solid. It pairs with DNA, flask and atom icons in the same science set; works down to 24px because the layout is only three shapes.

This is the solid black filled version of the linear molecular structure 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.
