WebbAbout Nitrogen is the lightest element in Periodic Table Group 15, also known as the pnictogens. Two atoms of the element bind to form dinitrogen, a colourless and odourless diatomic gas, at a specific temperature and pressure. Dinitrogen constitutes approximately 78 percent of the Earth's atmosphere, making it the most widely uncombined element. The pnictogens consist of two non-metals (one gas, one solid), two metalloids, one metal, and one element with unknown chemical properties. All the elements in the group are solids at room temperature, except for nitrogen which is gaseous at room temperature. Visa mer A pnictogen is any of the chemical elements in group 15 of the periodic table. Group 15 is also known as the nitrogen group or nitrogen family. Group 15 consists of the elements nitrogen (N), phosphorus Visa mer The nitrogen compound sal ammoniac (ammonium chloride) has been known since the time of the Ancient Egyptians.
