Nitrogen is a relatively inert molecule. It has an atomic number of seven, meaning a nitrogen atom has seven protons (and seven electrons). Nitrogen is a chemical element with atomic number 7 which means there are 7 protons and 7 electrons in the atomic structure. Common chemical compounds are also provided for many elements. It has five electrons in its outer shell and is, therefore, trivalent in most compounds. 1. Comprehensive data on the chemical element Nitrogen is provided on this page; including scores of properties, element names in many languages, most known nuclides of Nitrogen. Nitrogen plays an important role in the life of plants and animals on Earth through the nitrogen cycle. Chemical Properties of Nitrogen. This blanket of nitrogen helps to prevent the oxidation of the product. Nitrogen is a nonmetal found throughout our world. Nitrogen is a nonmetal with an electronegativity of 3.04. It has a grade 3 electronegativity and in the periodic table it is represented by the letter “N”. The unique physical and chemical properties of nitrogen provide some … It is also the most common element of our air, in the form of nitrogen gas. Haber-Bosch’s method, The most famous elements in 5A group (Nitrogen properties, Preparation & compounds) Elements of p-block, General properties of group 5A elements (group 15) Liquid nitrogen is used as a refrigerant. Under normal conditions it is presented in a gaseous state and is called a diatomic or molecular gas. Nitrogen atoms have seven electrons and 7 protons with five electrons in the outer shell. Introduction. Nitrogen gas is produced in large volumes in both gas and liquid form by cryogenic distillation, and cryogenic processes can produce very pure nitrogen. Nitrogen is a chemical element that has a high negative charge. The chemical symbol for Nitrogen is N. Nitrogen is a colourless, odourless unreactive gas that forms about 78% of the earth’s atmosphere. The triple bond in molecular nitrogen (N 2) is one of the strongest known. What is nitrogen? It is common in organisms, especially in proteins, which are rich with amine groups. When I worked in a surfactant company nitrogen was often used to protect the products made by using a blanket of nitrogen. Nitrogen is one of the most common elements on Earth, and it is one of many nonmetals. Nitrogen’s inert qualities find use in the chemical and petroleum industries to blanket storage tanks with an inert layer of gas. Nitrogen is a gas at room temperature.

Nitrogen, for example, is a gas that liquefies at about −200° C and freezes around −210° C, whereas bismuth is a solid melting at 271° C and boiling at about 1,560° C. Chemically, too, the range in properties is wide, nitrogen and phosphorus being typical nonmetals; arsenic and antimony, metalloids; and bismuth, a metal. The attractive properties of active carbons are determined by the well-developed surface area and the type, number and mode of bonding of different heteroatoms (oxygen, sulphur, nitrogen, boron, phosphorus, chlorine) with the carbon’s surface , , , , , .From among the modified carbon sorbents of great interest are the nitrogen-enriched ones.
