phos·pho·rus

 (fŏs′fər-əs)
n.
1. Symbol P 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 (or violet). An essential element for biological cells, 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) 44.15°C; boiling point 280.5°C; specific gravity (white) 1.82, (red) 2.16, (black) 2.25 to 2.69; valence 3, 4, 5. See Periodic Table.
2. A phosphorescent substance.
3. Phosphorus Astronomy See Lucifer.

[Modern Latin phōsphorus, substance or organism that emits light, phosphorus, Latin Phōsphorus, morning star, from Greek phōsphoros, bringing light, morning star : phōs, light; see bhā- in Indo-European roots + -phoros, -phorous.]

phosphorus

(ˈfɒsfərəs)
npl phosphori (-rai)
1. (Elements & Compounds) an allotropic nonmetallic element occurring in phosphates and living matter. Ordinary phosphorus is a toxic flammable phosphorescent white solid; the red form is less reactive and nontoxic: used in matches, pesticides, and alloys. The radioisotope phosphorus-32 (radiophosphorus), with a half-life of 14.3 days, is used in radiotherapy and as a tracer. Symbol: P; atomic no: 15; atomic wt: 30.973 762; valency: 3 or 5; relative density: 1.82 (white), 2.20 (red); melting pt: 44.1°C (white); boiling pt: 280°C (white)
2. (General Physics) a less common name for a phosphor
[C17: via Latin from Greek phōsphoros light-bringing, from phōs light +pherein to bring]
