Surface Forms

dihydrogen singular

Morphology

dihydrogen = hydrogen (transparent) = di + hydrogen

The noun denotes a molecule composed of two hydrogen atoms and is formed by the same productive chemical prefixation 'di-' + 'hydrogen'.

Etymology

Dihydrogen as a molecule is written H₂, and the name shows its origin: di- 'two' plus hydrogen from hydro- 'water' and -gen 'maker'. That's why dihydrogen is two hydrogen atoms joined together and why burning hydrogen can form water.
