Name: Nitrogen Symbol: N Atomic number: 7 Atomic weight: 14.0067 (2) [see notes g r] Standard state: gas at 298 K CAS Registry ID: 7727-37-9 Group in periodic table: 15 Group name: Pnictogen Period in periodic table: 2 Block in periodic table: pblock Color: colorless Classification: Nonmetallic The result of touching nitrogen triiodide (NI3)! Nitrogen triiodide is dangerously percussion sensitive (only to be demonstrated by a professionally qualified chemist following a legally satisfactory hazard assessment). Improperly done, this reaction is dangerous! Nitrogen is a Group 15 element. Nitrogen makes up about 78% of the atmosphere by volume but the atmosphere of Mars contains less than 3% nitrogen. The element seemed so inert that Lavoisier named it azote, meaning "without life". However, its compounds are vital components of foods, fertilizers, and explosives. Nitrogen gas is colorless, odorless, and generally inert. As a liquid it is also colorless and odorless. Nitrogen's name comes from nitrogenium a combination of words of Latin and Greek that means "native soda forming". Until the late 1700s gases were poorly understood by chemists. They often wondered what air was made of. In the 1770's, a Scottish physician and chemist Daniel Rutherford (17491819) performed a simple experiment with which he discovered nitrogen. Rutherford began with an empty bottle that he turned upside down in a pan of water, so that the air was trapped. A burning candle was placed inside the bottle with the trapped air, causing the water to rise a bit. Why did this happen? The part of the air that seemed to "disappear" when the candle was burned was oxygen gas, and the part of the air that did not "disappear" Rutherford discovered was nitrogen. Elements that go with nitrogen are hydrogen, chlorine, carbon, oxygen, fluorine, and iodine because they have valence electrons that match with nitrogen. http://www.last.fm/music/The+Outlaws/_/Green%2BGrass%2B%2526%2BHigh%2BTides I picked this element because if you don’t have nitrogen there wouldn’t be any green grass or water so it fits pretty good.
