Definitions of phosphorus

  1. 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
  2. a planet ( usually Venus) seen just before sunrise in the eastern sky
  3. The morning star; Phosphor.
  4. A poisonous nonmetallic element of the nitrogen group, obtained as a white, or yellowish, translucent waxy substance, having a characteristic disagreeable smell. 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 compined, 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.
  5. Hence, any substance which shines in the dark like phosphorus, as certain phosphorescent bodies.
  6. An element that has the atomic symbol P, atomic number 15, and atomic weight 31. It is an essential element in the diet, a major component of the mineral phase of bone, and is abundant in all tissues, being involved in some form in almost all metabolic processes. ( From Dorland, 27th ed)
  7. An inflammable substance which gives out light without beat.
  8. A luminous poison obtained from bones; a valuable tonic.
  9. The morning- star: a yellowish substance, like wax, inflammable and luminous in the dark.
  10. An elementary combustible substance, faintly luminous in the dark.
  11. A combustible mineral element that ignites by moderate heat, as of friction.
  12. A combustible substance of a yellowish colour, and luminous in the dark.
  13. An elementary substance of a waxlike consistence, easily made to burn, even by the heat of the fingers or by friction, always luminous in the dark in its ordinary state; the morning star.
