It exists primarily as diatomic molecules (N₂), making it inert and stable under standard conditions. Nitrogen is a chemical element; it has symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
Understanding its uses is pivotal for educators and students alike to appreciate this element’s versatility. The oxidation state of an atom is a measure of the degree of oxidation of an atom. It is defined as being the charge that an atom would have if all bonds were ionic.
Nitrogen is found to have either 3 or 5 valence electrons and lies at the top of Group 15 on the periodic table. It can have either 3 or 5 valence electrons because it can bond in the outer 2p and 2s orbitals. Molecular nitrogen (\(N_2\)) is not reactive at standard temperature and pressure and is a colorless and odorless gas. Nitrogen uses a variety of different oxidation numbers from +1 to +5 for oxide compounds. Almost all the oxides that form are gasses, and exist at 25 degrees Celsius.
Where the element is most commonly found in nature, and how it is sourced commercially. Relative atomic massThe mass of an atom relative to that of carbon-12. This is approximately the sum of the number of protons and neutrons in the nucleus. Where more than one isotope exists, the value given is the abundance weighted average.
Nitrogen forms strong bonds because of its ability to form a triple bond with itself and other elements. Thus, there is a lot of energy in the compounds of nitrogen. Now, nitrogen is commonly used to preserve food and as a fertilizer.

- Here is a comprehensive guide to the commercial production of nitrogen, aimed at providing educators with detailed insights into the process.
Chemistry and compounds
Elemental nitrogen is usually produced from air by pressure swing adsorption technology. Many industrially important compounds, such as ammonia, nitric acid, organic nitrates (propellants and explosives), and cyanides, contain nitrogen. The extremely strong triple bond in elemental nitrogen (N≡N), the second strongest bond in any diatomic molecule after carbon monoxide (CO),9 dominates nitrogen chemistry.
Nitrogen & its Compounds (Cambridge (CIE) A Level Chemistry): Revision Note
It is one of the most produced industrial gases, and is produced commercially as a gas and a liquid. Nitrogen is a fundamental element that permeates life, industry, and the environment. With this guide, embrace nitrogen’s complexities and its vital contributions to our world. Use this knowledge responsibly and innovatively for a sustainable future. Nitrides are compounds of nitrogen with a less electronegative atom; in other words they are compounds with atoms that have a less full valence shell.
Boiling point The temperature at which the liquid–gas phase change occurs. Melting pointThe temperature at which the solid–liquid phase change occurs. Electron configurationThe arrangements of electrons above limefx scam the last (closed shell) noble gas.
Nitrogen is essential and non-toxic in its molecular form (N₂), but certain nitrogen compounds or excessive amounts can be harmful. Nitrogen, a versatile and widely abundant element, is crucial in various sectors due to its unique properties. It’s the most abundant gas in Earth’s atmosphere and has numerous applications in the industrial, technological, and scientific sectors.
Nitrogen is a gas, making up about 78% of Earth’s atmosphere by volume; it’s colorless, odorless, and mostly inert.

It is given by the ratio of the pressure on a body to the fractional decrease in volume.
- Pumping the bags full of inert nitrogen gas means there’s no oxygen for the bacteria to survive, keeping the crisps fresher for longer.
- SublimationThe transition of a substance directly from the solid to the gas phase without passing through a liquid phase.
- Nitride ions are very strong bases, especially in aqueous solutions.
- Many industrially important compounds, such as ammonia, nitric acid, organic nitrates (propellants and explosives), and cyanides, contain nitrogen.

Pumping the bags full of inert nitrogen gas means there’s no oxygen for the bacteria to survive, keeping the crisps fresher for longer. When mixed with water, nitride will form ammonia; the nitride ion acts as a very strong base. Nitrogen has two naturally occurring isotopes, nitrogen-14 and nitrogen-15, which can be separated with chemical exchanges or thermal diffusion. Nitrogen also has isotopes with masses of 12, 13, 16, and 17, but they are radioactive. A reminder that emergency services were called shortly before 11am this morning following reports that a woman had suffered a medical episode. It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system.
He showed that there was residual gas that did not support combustion as did oxygen or carbon dioxide. Nitrogen, which makes up about 78% of our atmosphere, is a colorless, odorless, tasteless and chemically unreactive gas at room temperature. Its name is derived from the Greek nitron + genes for soda forming. For many years during the 1500’s and 1600’s, scientists hinted that there was another gas in the atmosphere besides carbon dioxide and oxygen. It was not until the 1700’s that scientists could prove there was in fact another gas that took up mass in the atmosphere of the Earth.
Specific heat capacity is the amount of energy needed to change the temperature of a kilogram of a substance by 1 K. The number of atoms of the element per 1 million atoms of the Earth’s crust. First ionisation energyThe minimum energy required to remove an electron from a neutral atom in its ground state. Electronegativity (Pauling scale)The tendency of an atom to attract electrons towards itself, expressed on a relative scale.
At standard temperature and pressure, two atoms of the element bond to form N2, a colourless and odourless diatomic gas. N2 forms about 78% of Earth’s atmosphere, making it the most abundant chemical species in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth. Discover Nitrogen, a fundamental element that pairs with hydrogen to form the building blocks of life. This guide takes you through the journey of Nitrogen’s role in the atmosphere, its usage in various industries, and its presence in organic compounds. Understanding Nitrogen is key in fields ranging from agriculture to medicine.

Represented by the symbol ‘N’ and atomic number 7, it is a nonmetal with five electrons in its outer shell. Nitrogen is crucial for all living organisms as it is a key component of amino acids, proteins, and nucleic acids (DNA & RNA).
The atomic number of each element increases by one, reading from left to right. Nitride ions are very strong bases, especially in aqueous solutions. We’re also on Facebook/theliverpoolecho – your must-see news, features, videos and pictures throughout the day from the Liverpool ECHO.
Of that amount, the majority is used to manufacture ammonia (\(NH_3\)) via the Haber process. Nitrogen is a non-metal element that occurs most abundantly in the atmosphere; nitrogen gas (N2) https://limefx.club/ comprises 78.1% of the volume of the Earth’s air. Compounds of nitrogen are found in foods, explosives, poisons, and fertilizers. Nitrogen is found in DNA in the form of nitrogenous bases as well as in neurotransmitters.
