Its atmosphere consists of over 98% nitrogen. Saturn's largest moon, Titan, is the only moon in the solar system with a dense atmosphere.It forms negatively charged ions (anions) that readily react with other nonmetals to form covalent bonds. Damage occurs from pressure generated by expanding gas as well as from the cold temperature. However, the liquid nitrogen is used to produce fog in cocktails, there is a real danger of ingesting the liquid. When liquid nitrogen is used to make ice cream, the nitrogen vaporizes. While the Leidenfrost effect protects skin from very brief exposure (less than one second), ingesting liquid nitrogen can cause severe injury. Liquid nitrogen is a cryogenic fluid, capable of freezing skin on contact.One way to prepare nitrogen gas is by liquefaction and fractional distillation from the atmosphere.Nitrogen is responsible for the orange-red, blue-green, blue-violet, and deep violet colors of the aurora.Your body is 3% nitrogen by weight. All living organisms contain this element. Nitrogen compounds are found in foods, fertilizers, poisons, and explosives.The other gases in air are present in much lower concentrations. Nitrogen was sometimes referred to as "burnt" or " dephlogisticated" air, since air that no longer contains oxygen is almost all nitrogen.Credit for the discovery of the element is generally given to Daniel Rutherford, who found it could be separated from air in 1772. The name became nitrogen, which derives from the Greek word nitron, which means "native soda" and genes, which means "forming". The French chemist Antoine Laurent Lavoisier named nitrogen azote, meaning "without life".Nitrogen gas is relatively inert, but soil bacteria can 'fix' nitrogen into a form that plants and animals can use to make amino acids and proteins.Like other elements in this group, it is a poor conductor of heat and electricity and lacks metallic luster in solid form. ![]() For example, nitrogen gas is found in the atmosphere of Mars at levels of about 2.6 percent. While the gas is common on Earth, it's not so abundant on other planets. It's estimated to be the 5th or 7th most abundant element in the Solar System and Milky Way (present in much lower amounts than hydrogen, helium, and oxygen, so it's hard to get a hard figure). It's the most common uncombined (pure) element on Earth. Nitrogen gas (N 2) makes up 78.1% of the volume of the Earth's air.Nitrogen is odorless, tasteless, and colorless gas at room temperature and pressure. Nitrogen is atomic number 7, which means each nitrogen atom has 7 protons.Appearance: Nitrogen is an odorless, flavorless, transparent gas under ordinary temperatures and pressure.
