Linear Molecular Structure black outline icon

About the Linear Molecular Structure black outline 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 black outline version of the linear molecular structure icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
