- n. A highly reactive, poisonous, nonmetallic element occurring naturally in phosphates, especially apatite, and existing in three allotropic forms, white (or sometimes yellow), red, and black. An essential constituent of protoplasm, it is used in safety matches, pyrotechnics, incendiary shells, and fertilizers and to protect metal surfaces from corrosion. Atomic number 15; atomic weight 30.9738; melting point (white) 44.1°C; boiling point 280°C; specific gravity (white) 1.82; valence 3, 5. See Table at element.
- n. A phosphorescent substance.

- n. a chemical element (symbol P) with an atomic number of 15, that exists in several allotropic forms.
- n. any substance exhibiting phosphorescence; a phosphor

- n. The morning star; Phosphor.
- n. 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. The molecule contains four atoms. Symbol P. Atomic weight 31.0.
- n. Hence, any substance which shines in the dark like phosphorus, as certain phosphorescent bodies.
from The Century Dictionary and Cyclopedia
- n. [capitalized] The morning star; Phosphor.
- n. Chemical symbol, P; atomic weight, 31; specific gravity, 1.826. A solid non-metallic combustible substance, hitherto undecomposed, not found by itself in nature, but occurring chiefly in combination with oxygen, calcium, and magnesium.
- n. A small bottle containing 12 grains of phosphorus melted in half an ounce of olive-oil. On being uncorked in the dark this solution emits light enough to illuminate the dial of a watch, and it will retain this property for several years if not too frequently used.
- n. [With a pl. phosphori (-rī).] In early use, a substance which emits light otherwise than as the result of ordinary combustion.

- n. a multivalent nonmetallic element of the nitrogen family that occurs commonly in inorganic phosphate rocks and as organic phosphates in all living cells; is highly reactive and occurs in several allotropic forms
In workers exposed to the fumes of yellow phosphorus, the bone may be so devitalised that it readily becomes infected with pyogenic organisms and undergoes a process of cario-necrosis -- the _phosphorus necrosis_ of the older writers.
But is there no method of acidifying phosphorus in a slighter manner, so as to form _phosphorus_ acid?
The name phosphorus comes from the Greek word phosphoros, which means bringer of light.
I mean, we call it phosphorus but you can call it whatever you want in the end.
The ore itself takes millions of years to form, and the prospect of extracting phosphorus from the sea bed presents massive technological and financial challenges.
Indeed, in the online version of the story, the word phosphorus is set as a hotlink to an article on the controversy over the battlefield use of phosphorus, indicating that at least someone at the Times has integrity and a good news sense.www. thiscantbehappening.net
Though phosphorus is used as a concealment weapon, that is a canard, because it is so dangerous that it cannot be used for local concealment because it would kill our troops if the wind shifted.
As I noted above, phosphorus is not spelled ‘- ous’ in the United States.
Me, White phosphorus is neither illegal nor a weapon of mass destruction.
“Use of white phosphorus is not specifically banned by any treaty, however the 1980 Convention on Conventional Weapons (Protocol III) prohibits the use of incendiary weapons against civilian populations or by air attack against military forces that are located within concentrations of civilians.”
