Hydrogen
(gcide) | Hydrogen \Hy"dro*gen\, n. [Hydro-, 1 + -gen: cf. F.
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.
[1913 Webster]
Note: Although a gas, hydrogen is chemically similar to the
metals in its nature, having the properties of a weak
base. It is, in all acids, the base which is replaced
by metals and basic radicals to form salts. Like all
other gases, it is condensed by great cold and pressure
to a liquid which freezes and solidifies by its own
evaporation. It is absorbed in large quantities by
certain metals (esp. palladium), forming alloy-like
compounds; hence, in view of quasi-metallic nature, it
is sometimes called hydrogenium. It is the typical
reducing agent, as opposed to oxidizers, as oxygen,
chlorine, etc.

Hydrogen dioxide, a thick, colorless liquid, H2O2,
resembling water, but having a bitter, sour taste,
produced by the action of acids on barium peroxide. It
decomposes into water and oxygen, and is manufactured in
large quantities for an oxidizing and bleaching agent.
Called also oxygenated water.
Hydrogen oxide, a chemical name for water, H?O.
Hydrogen sulphide, a colorless inflammable gas, H2S,
having the characteristic odor of bad eggs, and found in
many mineral springs. It is produced by the action of
acids on metallic sulphides, and is an important chemical
reagent. Called also sulphureted hydrogen.

if the obligor shall do a certain act, appear at a certain
place, conform to certain rules, faithfully perform
certain duties, or pay a certain sum of money, on or
before a time specified, the obligation shall be void;
otherwise it shall remain in full force. If the condition
is not performed, the bond becomes forfeited, and the
obligor and his heirs are liable to the payment of the
whole sum. --Bouvier. --Wharton.

with their ends toward the face of the wall, called
headers, and the next course of bricks with their lengths
parallel to the face of the wall, called stretchers;
Flemish bond (Fig.2), where each course consists of
headers and stretchers alternately, so laid as always to
break joints; Cross bond, which differs from the English
by the change of the second stretcher line so that its
joints come in the middle of the first, and the same
position of stretchers comes back every fifth line;
Combined cross and English bond, where the inner part of
the wall is laid in the one method, the outer in the
other.
[1913 Webster]
9. (Chem.) A unit of chemical attraction between atoms; as,

covalent bond, an attractive force between two atoms of a
molecule generated by the merging of an electron orbital
of each atom into a combined orbital in the molecule. Such
bonds vary in strength, but in molecules of substances
typically encountered in human experience (as, water or
alcohol) they are sufficiently strong to persist and
maintain the identity and integrity of the molecule over
appreciable periods of time. Each such bond satisfies one
unit of valence for each of the atoms thus bonded.
Contrasted with hydrogen bond, which is weaker and does
not satisfy the valence of either atom involved.
double bond, triple bond, a covalent bond which
involves the merging of orbitals of two (or three)
electrons on each of the two connected atoms, thus
satisfying two (or three) units of valence on each of the
bonded atoms. When two carbon atoms are thus bonded, the
bond (and the compound) are said to be unsaturated.
Bond debt (Law), a debt contracted under the obligation of
a bond. --Burrows.
hydrogen bond, a non-covalent bond between hydrogen and
another atom, usually oxygen or nitrogen. It does not
involve the sharing of electrons between the bonded atoms,
and therefore does not satisfy the valence of either atom.
Hydrogen bonds are weak (ca. 5 kcal/mol) and may be
frequently broken and reformed in solution at room
temperature.
Bond of a slate or lap of a slate, the distance between
the top of one slate and the bottom or drip of the second
slate above, i. e., the space which is covered with three
thicknesses; also, the distance between the nail of the
under slate and the lower edge of the upper slate.

it longitudinally.

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

metals in its nature, having the properties of a weak
base. It is, in all acids, the base which is replaced
by metals and basic radicals to form salts. Like all
other gases, it is condensed by great cold and pressure
to a liquid which freezes and solidifies by its own
evaporation. It is absorbed in large quantities by
certain metals (esp. palladium), forming alloy-like
compounds; hence, in view of quasi-metallic nature, it
is sometimes called hydrogenium. It is the typical
reducing agent, as opposed to oxidizers, as oxygen,
chlorine, etc.
