Amorphous phosphorus
(gcide) | Phosphorus \Phos"phor*us\ (f[o^]s"f[o^]r*[u^]s), n.; pl.
Phosphori (f[o^]s"f[o^]r*[imac]). [L., the morning star,
Gr. fwsfo`ros, lit., light bringer; fw^s light + fe`rein to
bring.]
1. The morning star; Phosphor.
[1913 Webster]
2. (Chem.) A poisonous nonmetallic element of the nitrogen
group, obtained as a white, or yellowish, translucent waxy
substance, having a characteristic disagreeable smell;
this waxy allotropic form is also called {yellow
phosphorus}, to distinguish it from another allotropic
form, red phosphorus. It is very active chemically, must
be preserved under water, and unites with oxygen even at
ordinary temperatures, giving a faint glow, -- whence its
name. It always occurs combined, usually in phosphates, as
in the mineral apatite, in bones, etc. It is used in the
composition on the tips of friction matches, and for many
other purposes. It is an essential component of the
genetic material of all living organisms. The molecule
contains four atoms. Symbol P. Atomic weight 31.0.
[1913 Webster]
3. (Chem.) Hence, any substance which shines in the dark like
phosphorus, as certain phosphorescent bodies.
[1913 Webster]
Bologna phosphorus (Chem.), sulphide of barium, which
shines in the dark after exposure to light; -- so called
because this property was discovered by a resident of
Bologna. The term is sometimes applied to other compounds
having similar properties.
Metallic phosphorus (Chem.), an allotropic modification of
phosphorus, obtained as a gray metallic crystalline
substance, having very inert chemical properties. It is
obtained by heating ordinary phosphorus in a closed vessel
at a high temperature.
Phosphorus disease (Med.), a disease common among workers
in phosphorus, giving rise to necrosis of the jawbone, and
other symptoms.
Red phosphorus, or Amorphous phosphorus (Chem.), an
allotropic modification of phosphorus, obtained as a dark
red powder by heating ordinary phosphorus in closed
vessels. It is not poisonous, is not phosphorescent, and
is only moderately active chemically. It is valuable as a
chemical reagent, and is used in the composition of the
friction surface on which safety matches are ignited.
Solar phosphori (Chem.), phosphorescent substances which
shine in the dark after exposure to the sunlight or other
intense light.
yellow phosphorus (Chem.), the waxy yellow allotropic form
of elemental phosphorus. See also phosphorus[2].

Amorphous sulphur
(gcide) | Sulphur \Sul"phur\, n. [L., better sulfur: cf. F. soufre.]
1. (Chem.) A nonmetallic element occurring naturally in large
quantities, either combined as in the sulphides (as
pyrites) and sulphates (as gypsum), or native in volcanic
regions, in vast beds mixed with gypsum and various earthy
materials, from which it is melted out. Symbol S. Atomic
weight 32. The specific gravity of ordinary octohedral
sulphur is 2.05; of prismatic sulphur, 1.96.
[1913 Webster]
Note: It is purified by distillation, and is obtained as a
lemon-yellow powder (by sublimation), called flour, or
flowers, of sulphur, or in cast sticks called roll
sulphur, or brimstone. It burns with a blue flame and a
peculiar suffocating odor. It is an ingredient of
gunpowder, is used on friction matches, and in medicine
(as a laxative and insecticide), but its chief use is
in the manufacture of sulphuric acid. Sulphur can be
obtained in two crystalline modifications, in
orthorhombic octahedra, or in monoclinic prisms, the
former of which is the more stable at ordinary
temperatures. Sulphur is the type, in its chemical
relations, of a group of elements, including selenium
and tellurium, called collectively the sulphur group,
or family. In many respects sulphur resembles oxygen.
[1913 Webster]
2. (Zool.) Any one of numerous species of yellow or orange
butterflies of the subfamily Pierinae; as, the clouded
sulphur (Eurymus philodice syn. Colias philodice),
which is the common yellow butterfly of the Eastern United
States.
[1913 Webster]
Amorphous sulphur (Chem.), an elastic variety of sulphur of
a resinous appearance, obtained by pouring melted sulphur
into water. On standing, it passes back into a brittle
crystalline modification.
Liver of sulphur. (Old Chem.) See Hepar.
Sulphur acid. (Chem.) See Sulphacid.
Sulphur alcohol. (Chem.) See Mercaptan.
Sulphur auratum [L.] (Old Chem.), a golden yellow powder,
consisting of antimonic sulphide, Sb2S5, -- formerly a
famous nostrum.
Sulphur base (Chem.), an alkaline sulphide capable of
acting as a base in the formation of sulphur salts
according to the old dual theory of salts. [Archaic]
Sulphur dioxide (Chem.), a colorless gas, SO2, of a
pungent, suffocating odor, produced by the burning of
sulphur. It is employed chiefly in the production of
sulphuric acid, and as a reagent in bleaching; -- called
also sulphurous anhydride, and formerly {sulphurous
acid}.
Sulphur ether (Chem.), a sulphide of hydrocarbon radicals,
formed like the ordinary ethers, which are oxides, but
with sulphur in the place of oxygen.
Sulphur salt (Chem.), a salt of a sulphacid; a sulphosalt.
Sulphur showers, showers of yellow pollen, resembling
sulphur in appearance, often carried from pine forests by
the wind to a great distance.
Sulphur trioxide (Chem.), a white crystalline solid, SO3,
obtained by oxidation of sulphur dioxide. It dissolves in
water with a hissing noise and the production of heat,
forming sulphuric acid, and is employed as a dehydrating
agent. Called also sulphuric anhydride, and formerly
sulphuric acid.
Sulphur whale. (Zool.) See Sulphur-bottom.
Vegetable sulphur (Bot.), lycopodium powder. See under
Lycopodium.
