Used mainly in scientific contexts, particularly when discussing chemical makeup of molecules.

Chemistry Specific

Diatomic refers to a pair of atoms, not parts that can be seen with the naked eye.

Not Always Visible

Diatomic is often confused with 'diagram,' but they have different meanings.

Common Misconception

 Those holes you see there are very filtered-down, watered-down versions of the extremity of the diatomic structures. It goes with the flow of the polymer and you'll see -- there's an image coming up right now that shows the full thing. It's great to have companies in Italy who support this way of dreaming.
