Surface Forms

dioxide singular
dioxides plural

Morphology

dioxide = oxide + di (transparent) = di + oxide

Formed by the combining form 'di-' meaning 'two' plus 'oxide', so the meaning 'two oxygen atoms' is directly derived.

Etymology

The word dioxide comes from di- meaning 'two' and oxide, which shows it has oxygen. So a dioxide is a chemical with 'two' oxygen atoms joined to another element, which is why carbon dioxide has two oxygen atoms in each molecule.
