phos·pho·rus  (fsfr-s)

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. 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.

2. A phosphorescent substance.

phosphorus [ˈfɒsfərəs]

n

1. (Chemistry / 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.: 30.973762; valency: 3 or 5; relative density: 1.82 (white), 2.20 (red); melting pt.: 44.1°C (white); boiling pt.: 280°C (white)

2. (Physics / General Physics) a less common name for a phosphor

[via Latin from Greek phōsphoros light-bringing, from phōs light + pherein to bring]

phosphorus  (fsfr-s)

Symbol P

A highly reactive, poisonous nonmetallic element occurring naturally in phosphates, especially in the mineral apatite. It exists in white (or sometimes yellow), red, and black forms, and is an essential component of protoplasm. Phosphorus is used to make matches, fireworks, 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 Periodic Table.
