Why nitrogen is a gas?
Nitrogen due to small size and high electronegativity forms ρπ−ρπ multiple bonds and exists as a diatomic molecule. These molecules are held together by weak Van der Waal forces and hence N2 exist as a gas at room temperature.

The periodic table game available on this page is for entertainment purposes only, and should not be used to grade students on their knowledge of chemical elements.
Does the Modern Periodic Table Change? If So, How and Who Does That?
The periodic table as we know it today is managed by the International Union of Pure and Applied Chemistry, or IUPAC (eye-you-pack).
What is 15 N used for?
Artificially enriched 15 N tracers are used to study movement and transformation of nitrogen in biological and environmental systems, such as the uptake and loss of nitrogen fertilizers by crops (Fig. IUPAC.7.1). A common experiment involves introducing an isotopically labeled compound into the environment and then analyzing various samples taken from the environment for the presence of the enriched isotope to determine where the labeled compound moved and whether it transformed into other compounds (Fig. IUPAC.7.2). Artificially enriched 15 N is used to study uptake and dispersal of nitrogen in feed supplies used in food production industries such as aquaculture [82].
What is the isotope-amount ratio of nitrogen?
Variations in the isotope-amount ratio n ( 15 N)/n ( 14 N) are used to determine sources of nitrogen contamination in the atmosphere, oceans, groundwater, and rivers, where the isotopic composition of a contaminant molecule preserves evidence of the nitrogen sources and processes involved in its creation. An example is nitrate derived from artificial fertilizer, manure, power-plant emissions, or natural sources [87], [88], [89].
How does isotopic fractionation affect food chains?
Isotopic fractionation can cause the isotope-amount ratio n ( 15 N)/n ( 14 N) to increase systematically through food chains through assimilation of nitrogen compounds in biomolecules such as proteins. When lower-order organisms are ingested by higher-order organisms, 15 N may be selectively retained and 14 N may be selectively excreted such that higher-order organisms tend to have higher n ( 15 N)/n ( 14 N) ratios than their food sources. Isotopic fractionation occurs as a result of assimilation, storage, and excretion of proteins and other nitrogen compounds. Biologists can use isotope-amount ratio n ( 15 N)/n ( 14 N) measurements to test hypotheses about predator-prey relations and detect disruptions to trophic structure of ecosystems that might be caused by toxic contaminants, invasive species, or harvesting of organisms. Similar principles are used to detect differences in diets among animals, including humans, both today and in the distant past [79], [80], [81].
What is the isotopic composition of pseudoephedrine?
Stable hydrogen, carbon, and nitrogen isotopic compositions are used to determine the origin of pseudoephedrine from seized methyl-amphetamine made from the pseudoephedrine (drug used as a nasal decongestant or as a stimulant) [91].
Where did nitrogen come from?
The name derives from the Latin nitrum and Greek nitron for "native soda" and genes for "forming". Nitrogen was discovered by the Scottish physician and chemist Daniel Rutherford in 1772.
How does nature produce nitrogen?
In other words, Nature has provided a method to produce nitrogen for plants to grow. Animals eat the plant material where the nitrogen has been incorporated into their system, primarily as protein. The cycle is completed when other bacteria convert the waste nitrogen compounds back to nitrogen gas.
How much of the atmosphere is nitrogen?
Nitrogen gas (N 2) makes up 78.1% of the Earth’s air, by volume. The atmosphere of Mars, by comparison, is only 2.6% nitrogen. From an exhaustible source in our atmosphere, nitrogen gas can be obtained by liquefaction and fractional distillation. Nitrogen is found in all living systems as part of the makeup of biological compounds.
How many isotopes of nitrogen are there?
There are two stable isotope of nitrogen, nitrogen-14 and nitogen-15. Nitrogen-14 is very abundant and makes about 99.6% of naturally occurring nitrogen. There isotopes are produced in the stars. Nitrogen-15 was discovered in 1929 by S.M. Naude. There are ten artificially produced radioactive isotopes of nitrogen, ranging from nitrogen-12 to nitrogen-23.
What is the Greek word for nitrogen?
Earlier, Antoine Lavoisier used the term azote (Greek) meaning no life for nitrogen, which later became choke or to suffocate and the term pnictogens (Greek for choke) was assigned to Group 15 due to nitrogen. In 1970, nitrogene (French word) was given to the element by Antoine Chaptal and in 1974 it became nitrogen in English language.
What is the alpha phase of nitrogen?
The alpha phase is another allotropic form of nitrogen that it acquires by arranging in a cubic crystal when exposed to temperature lower than -237C. The density of liquid nitrogen is 0.808 g/mL which is about 80.8% denser than water.

It was known as aqua fortis the strong water. And mixture of hydrochloric and nitric acid was formed that has the ability to dissolve the Nobel metal and the king of metals, gold.
Which element has triple bonds?
The triple bonds present in N 2 are extremely strong and in fact are the second strongest bonds in elemental chemistry. Except for Nobel gases, nitrogen can react with almost every element in the periodic table and forms nitrides.
Is nitrogen a gas?
Nitrogen is a colorless and odorless gas. Liquid nitrogen resembles water in its appearance, as it is colorless. Nitrogen is a very light gas and is the lightest gas in its group (Group 15). Molecular nitrogen undergoes liquefaction at -195.79C and freezes at -210 C and acquire a beta hexagonal structural assembly [3].
