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