Facts about nitrogen
Here are a few interesting facts about nitrogen element.
- Rightnow, you are breathing the air that contains 78% nitrogen.
- Nitrogen is the 7th most abundant element present in the entire universe.
- The human body, plant body as well as animals possess nitrogen.
- In our body, the proteins, DNA & RNA contain nitrogen elements.
- The atmosphere of Titan (which is the largest moon of Saturn), has around 98% nitrogen.
- Liquid nitrogen is very cold and it can even burn your skin.
- The earth’s atmosphere contains 78% nitrogen in it.
Properties of nitrogen
Here is a list of some physical properties and chemical properties of nitrogen.
Physical properties of nitrogen
- Nitrogen is a colorless, odorless and tasteless gas.
- The liquid nitrogen looks like water.
- The melting point and boiling point of nitrogen are 63.23 K and 77.35 K respectively.
Chemical properties of nitrogen
- The nitrogen is a reactive gas and it always exists as a molecular nitrogen (N2).
- The N2 molecule has a triple bond between them, and these bonds have a very short bond length.
- The nitrogen is a reactive nonmetals and reacts with almost all the elements of the periodic table, except some noble gases.
- The nitrogen forms nitrides (which includes hydrides, oxides, fluorides, etc).
- The nitrides formed with alkali metals and alkaline earth metals are more ionic in nature as compared to other nitrides.
- The nitrogen reacts with hydrogen to form ammonia (NH3), which is a colorless alkaline gas.
- N2O (also known as laughing gas) is produced by the thermal decomposition of molten ammonium nitrate (NH4NO3) at 523 K temperature.
Uses of nitrogen
Here are some uses of the nitrogen element.
- Nitrogen is used in production of ammonia (NH3), which has wide industrial applications.
- Nitrogen is used in nitriding for case-hardening of steel.
- Nitrogen is also used in some aircraft fuel systems to reduce the fire hazard.
- Nitrogen is also used in filling tyres of vehicles, which reduces the running temperature of the tyre, as well as it also maintains the pressure.
- Liquid nitrogen is a cryogenic fluid which is used for cooling to low temperatures.
