Nitrogen has two stable isotopes: 14N and 15N. The first is much more common, making up This leads to an atomic weight of around Nitrogen is composed of 7 protons, 7 neutrons, and 7 electrons. Nitrogen is one of the very few stable nuclides with both an odd number of protons and of neutrons seven each and is the only one to make up a majority of its element.
Nitrogen is composed of 7 protons, 8 neutrons, and 7 electrons. Two sources of nitrogen are the positron emission of oxygen and the beta decay of carbon Nitrogen presents one of the lowest thermal neutron capture cross sections of all isotopes. Nitrogen is composed of 7 protons, 9 neutrons, and 7 electrons. In nuclear reactors, nitrogen can be used to detect leakages from steam generators.
Nitrogen is an isotope of nitrogen generated by neutron activation of oxygen contained in the water. It has a short half-life of 7. This decay is accompanied by emission of a very energetic gamma rays 6 MeV , which can readily penetrate the wall of the high-pressure piping and are therefore can be easily measured by ion chambers located on the hot leg piping of each coolant loop. The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus.
Therefore, the number of electrons in neutral atom of Nitrogen is 7. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other Z — 1 negative electrons in the atom.
Since the number of electrons and their arrangement are responsible for the chemical behavior of atoms, the atomic number identifies the various chemical elements. The configuration of these electrons follows from the principles of quantum mechanics. In the periodic table, the elements are listed in order of increasing atomic number Z. Many industrially important compounds, such as ammonia, nitric acid, organic nitrates propellants and explosives , and cyanides, contain nitrogen.
This causes difficulty for both organisms and industry in converting N2 into useful compounds, but at the same time means that burning, exploding, or decomposing nitrogen compounds to form nitrogen gas releases large amounts of often useful energy. It is defined as being the charge that an atom would have if all bonds were ionic. Uncombined elements have an oxidation state of 0. The sum of the oxidation states within a compound or ion must equal the overall charge.
Data for this section been provided by the British Geological Survey. An integrated supply risk index from 1 very low risk to 10 very high risk. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores.
The percentage of a commodity which is recycled. A higher recycling rate may reduce risk to supply. The availability of suitable substitutes for a given commodity.
The percentage of an element produced in the top producing country. The higher the value, the larger risk there is to supply. The percentage of the world reserves located in the country with the largest reserves. A percentile rank for the political stability of the top producing country, derived from World Bank governance indicators. A percentile rank for the political stability of the country with the largest reserves, derived from World Bank governance indicators.
Specific heat capacity is the amount of energy needed to change the temperature of a kilogram of a substance by 1 K. A measure of the stiffness of a substance. It provides a measure of how difficult it is to extend a material, with a value given by the ratio of tensile strength to tensile strain.
A measure of how difficult it is to deform a material. It is given by the ratio of the shear stress to the shear strain. A measure of how difficult it is to compress a substance. It is given by the ratio of the pressure on a body to the fractional decrease in volume. A measure of the propensity of a substance to evaporate. It is defined as the equilibrium pressure exerted by the gas produced above a substance in a closed system.

Discovery date Discovered by Daniel Rutherford Origin of the name The name is derived from the Greek 'nitron' and 'genes' meaning nitre forming.
Allotropes N 2. Glossary Group A vertical column in the periodic table. Fact box. Glossary Image explanation Murray Robertson is the artist behind the images which make up Visual Elements. Appearance The description of the element in its natural form. Biological role The role of the element in humans, animals and plants. Natural abundance Where the element is most commonly found in nature, and how it is sourced commercially.
Uses and properties. Image explanation. The wheat sheaf symbol and lightning reflect the importance of nitrogen to living things. Nitrogen is important to the chemical industry. It is used to make fertilisers, nitric acid, nylon, dyes and explosives.
To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process. Nitrogen gas is also used to provide an unreactive atmosphere. It is used in this way to preserve foods, and in the electronics industry during the production of transistors and diodes. Large quantities of nitrogen are used in annealing stainless steel and other steel mill products. Annealing is a heat treatment that makes steel easier to work. Liquid nitrogen is often used as a refrigerant.
It is used for storing sperm, eggs and other cells for medical research and reproductive technology.
