hydrog[`e]ne. So called because water is generated by its
combustion. See Hydra.] (Chem.)
A gaseous element, colorless, tasteless, and odorless, the
lightest known substance, being fourteen and a half times
lighter than air (hence its use in filling balloons), and
over eleven thousand times lighter than water. It is very
abundant, being an ingredient of water and of many other
substances, especially those of animal or vegetable origin.
It may by produced in many ways, but is chiefly obtained by
the action of acids (as sulphuric) on metals, as zinc, iron,
etc. It is very inflammable, and is an ingredient of coal gas
and water gas. It is standard of chemical equivalents or
combining weights, and also of valence, being the typical
monad. Symbol H. Atomic weight 1.
