6 things about nitrogen you should know

Nitrogen and its Facts

1. What is nitrogen?

Nitrogen is one of the most significant elements in organic chemistry. It is an inert diatomic gas. Nitrogen name is derived from a Greek word, ‘nitron’ and ‘genes’ which means nitre forming.

It is an element with symbol N and atomic number 7. Nitrogen is the lightest member of group 15 of the periodic table, often called the pnictogens.

2. Uses of nitrogen?

  • Liquid nitrogen is manly used as a refrigerant.

  • The gas is mainly used as an inert atmosphere to reduce fire hazards in some aircraft fuel system.

  • It used in light bulbs as an alternative to argon gas.

  • It is used in manufacturing stainless steel.

  • Nitrogen in many applications is a good blanketing gas because of its inert properties.

  • It is used to protect flammable or explosive solids or liquids from contact with air.

3.Function of Nitrogen in human body

Nitrogen is a one of the major factor in the creation of proteins which are essential for the creation of genetic material in the human body. It is necessary to all forms of life. Our body needs nitrogen, to build proteins in our muscles, skin, blood, hair, nails and DNA. Humans consume nitrogen through consumption of plants or animals which has consumed nitrogen-rich vegetation. Such foods include meat, fish, legumes, nuts, eggs, milk and few other dairy products.

4.What are some facts about Nitrogen?

  • Nitrogen gas makes up 78.1% of the quantity of the Earth's air. It's the most common pure element on Earth.

  • Nitrogen is present in all living organisms. Our body by weight is 3% nitrogen.

  • Nitrogen is sometimes called as 'burnt' or 'dephlogisticated' air, as the air that no longer contains oxygen is almost nitrogen. 

  • Saturn’s largest moon atmosphere contains more than 98% nitrogen.

5.Properties of nitrogen

  • Nitrogen in its both liquid and gaseous form is colorless and odorless.

  • It is also tasteless.

  • It is a poor conductor of heat and electricity.

  • Nitrogen is a non-metal, with atomic weight 14.0067 u, melting point as -321 °F and with boiling point as -320.42 °F.

  • Soil bacteria’s can fix nitrogen into a form that plants and animals uses to make amino acids and proteins.

  • A nitrogen atom has seven electrons and two stable isotopes (14N and 15N).

  • Nitrogen forms nine molecular oxides.

  • Nitrogen has 3-5 valences and it forms ions which are negatively charged.

  • Nitrogen is sometimes called as 'burnt' or 'dephlogisticated' air, as the air that no longer contains oxygen is almost nitrogen. 

6.What is nitrogen cycle?

The nitrogen cycle is the cycling process by which nitrogen is converted into various chemical forms, as it is circulated among the ecosystems. The conversion of nitrogen is carried out through biological or physical processes. The steps involved in nitrogen cycle are nitrogen fixation, nitrification, ammonifcation and denitrification.

Nitrogen is cycled naturally by all the living organisms using ‘nitrogen cycle’.
