Nitrogen
atomic symbol, N, nitrogen is the 7th element in the periodic table (atomic number 7), with an atomic weight of 14.01. Nitrogen is a group VB element and is relatively inert. Nitrogen is widely used during IC processing as an inert purge gas due to it's low cost, but must be used carefully because it will react under certain circumstances. For example, at >950oC nitrogen will thermally react with silicon to form silicon nitride in an oxygen starved environment. A small amount of oxygen is commonly added during furnace ramp-up and ramp-down in nitrogen when 950oC temperatures will be exceeded to suppress silicon nitride formation.

Nitrogen
(n.)
A colorless nonmetallic element, tasteless and odorless, comprising four fifths of the atmosphere by volume. 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, as ammonia, nitric acid, the cyanides, etc, and is a constituent of all organized living tissues, animal or vegetable. Symbol N. Atomic weight 14. It was formerly regarded as a permanent noncondensible gas, but was liquefied in 1877 by Cailletet of Paris, and Pictet of Geneva.

Nitrogen
Nitrogen Used to denote the familiar earthly element, and also its noumenon, of which it is the terrestrial manifestation. Thus, when air is said to stand for nitrogen in the enumeration of the four elements and when that which on earth is nitrogen is called the Son in the trinity Father-Mother-Son, it is evidently the noumenon which is meant (SD 1:253, 623). Nitrogen is also correlated with linga-sarira among the four lower principles.
Nitrogen plays the part of a vehicle, so far as oxygen of the air is concerned, but plays an extremely important part in plant life. The elements on earth are compound, being several generations below their original parents; and the gross elements contain all the subtle elements, but differ from each other in that each contains one of the subtle elements in a predominant proportion. It is often the subtle element that is meant when the word nitrogen is used in The Secret Doctrine.

Nitrogen
Name: nitrogen
Symbol: N
Atomic number: 7
Atomic weight: 14.00674 (7) g r
Group in periodic table: 15
Group name: Pnictogen
Period in periodic table: 2
Block in periodic table: p-block
CAS registry ID: 7727-37-9
Nitrogen is a Group 15 element. Nitrogen makes up about 78% of the atmosphere by volume but the atmosphere of Mars contains less than 3% nitrogen. The element seemed so inert that Lavoisier named it azote, meaning "without life". However, its compounds are vital components of foods, fertilizers, and explosives. Nitrogen gas is colourless, odourless, and generally inert. As a liquid it is also colourless and odourless.
When nitrogen is heated, it combines directly with magnesium, lithium, or calcium. When mixed with oxygen and subjected to electric sparks, it forms nitric oxide (NO) and then the dioxide (NO2). When heated under pressure with hydrogen in the presence of a suitable catalyst , ammonia forms (Haber process). Nitrogen is "fixed" from the atmosphere by bacteria in the roots of certain plants such as clover. Hence the usefulness of clover in crop rotation.

Nitrogen
Nitrogen (IPA: ) is a chemical element which has the symbol N and atomic number 7. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.1 y volume of Earth's atmosphere. Nitrogen is a constituent element of all living tissues and amino acids. Many industrially important compounds, such as ammonia, nitric acid, and cyanides, contain nitrogen.
