Many chemical compounds that are important for industrial purposes contain nitrogen ions.These include ammonia, nitric acid, nitrates and cyanides.Nitrogen comes in several oxidation states; -3, -2, - 1 / 3, +1, +3, +4, and +5.Each of those oxidation states has its set of compounds. Liquid nitrogen is often used as a refrigerant. The name nitrogen was therefore proposed from the observation, again first made by Cavendish that if the gases sparked with oxygen, and then the resulting nitrogen dioxide gases passed through alkali, nitre, otherwise known as saltpetre or potassium nitrate is formed. It's by far the most abundant element in its group in the periodic table and yet it is the last member of its family to be discovered. One way of remembering the identity of the pnictogen group is to remember the word starts with the symbols of two of its elements (P for phosphorus and N for nitrogen). The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems. Phosphorus, arsenic, bismuth and … Biological nitrogen fixation (BNF), discovered by Beijerinck in 1901, is carried out by a specialized group of prokaryotes. You may not further copy, alter, distribute or otherwise use any of the materials from this Site without the advance, written consent of the RSC. Nitrogen family elements share a similar electron configuration pattern and follow predictable trends in their chemical properties. Consequently, the discovery of nitrogen is usually accredited to one of Joseph Black's students, the Scottish scientist, Daniel Rutherford, who's also the uncle of the novelist and poet, Sir Walter Scott. What's in a name? Hydrogen was more carefully prepared and collected by the brilliant but reclusive millionaire scientist Henry Cavendish about a 100 years later.

The gas is the lightest of the nitrogen group of chemical elements, with the atomic number seven. First of all, if we know the atom symbol (or name), let's say N, we can open any periodic table and search for Nitrogen. The thing to remember about main-group elements is that the group number gives you the element's number of valence electrons. In spite of the fact that the N 2 molecule is unreactive, compounds containing nitrogen exist for virtually every element in the periodic table except those in Group VIIIA (He, Ne, Ar, and so on). Also Known As: Elements belonging to this group are also known as pnictogens, at term derived from the Greek word pnigein, which means "to choke". Arsenic and antimony are metalloids. Nitrogen iodide (NI3)(6CI,7CI,8CI,9CI) NITROGEN IODIDE. Nitrogen is the seventh element on the periodic table. Elements are organised into blocks by the orbital type in which the outer electrons are found. At the end of a star’s life, this nitrogen may be distributed into the galaxy. He passed air back and forth over heated charcoal which converted the oxygen in the air to carbon dioxide. Nitrogen is cycled naturally by living organisms through the ‘nitrogen cycle’.
