Nitrogen vs. Phosphorus

Nitrogennoun

(uncountable) A chemical element (symbol N) with an atomic number of 7 and atomic weight of 14.0067.

Nitrogennoun

(uncountable) Molecular nitrogen (N2), a colorless, odorless gas at room temperature.

Nitrogennoun

(countable) A specific nitrogen within a chemical formula, or a specific isotope of nitrogen

Nitrogennoun

A colorless nonmetallic element of atomic number 7, tasteless and odorless, comprising four fifths of the atmosphere by volume in the form of molecular nitrogen (N2). It is chemically very inert in the free state, and as such is incapable of supporting life (hence the name azote still used by French chemists); but it forms many important compounds, such as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic weight 14.007. It was formerly regarded as a permanent noncondensible gas, but was liquefied in 1877 by Cailletet of Paris, and Pictet of Geneva, and boils at -195.8 ° C at atmospheric pressure. Liquid nitrogen is used as a refrigerant to store delicate materials, such as bacteria, cells, and other biological materials.

Nitrogennoun

a common nonmetallic element that is normally a colorless odorless tasteless inert diatomic gas; constitutes 78 percent of the atmosphere by volume; a constituent of all living tissues

Nitrogen

Nitrogen is the chemical element with the symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772.

Phosphorusnoun

(chemistry) a chemical element (symbol P) with an atomic number of 15, that exists in several allotropic forms.

Phosphorusnoun

(obsolete) any substance exhibiting phosphorescence; a phosphor

Phosphorusnoun

The morning star; Phosphor.

Phosphorusnoun

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.

Phosphorusnoun

Hence, any substance which shines in the dark like phosphorus, as certain phosphorescent bodies.

Phosphorusnoun

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

Phosphorusnoun

a planet (usually Venus) seen just before sunrise in the eastern sky

Phosphorusnoun

the chemical element of atomic number 15, a poisonous, combustible non-metal which exists in two common allotropic forms, white phosphorus, a yellowish waxy solid which ignites spontaneously in air and glows in the dark, and red phosphorus, a less reactive form used in making matches.

Phosphorus

Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.
