The pnictogens

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.
