NITROGEN

Nitrogen is a chemical element with symbol N and atomic number 7. Elemental nitrogen is a colorless, odorless, tasteless, and mostly inert diatomic gas at standard conditions, constituting 78.09% by volume of Earth's atmosphere. The element nitrogen was discovered as a separable component of air, by Scottish physician Daniel Rutherford, in 1772. It belongs to the pnictogen family.Nitrogen occurs in all organisms, primarily in amino acids (and thus proteins) and also in the nucleic acids (DNA and RNA). The human body contains about 3% by weight of nitrogen, the fourth most abundant element in the body after oxygen, carbon, and hydrogen. The nitrogen cycle describes movement of the element from the air into the biosphere and organic compounds, then back into the atmosphere.From the Latin word nitrum, Greek nitronIt is called "burnt" or" dephlogisticated air," which meant air without oxygen.Characteristics: Nitrogen is a colorless, odorless, tasteless, diatomic and generally inert gas at standard temperature and pressure. At atmospheric pressure, nitrogen is liquid between 63 K and 77 K. Liquids colder than this are considerably more expensive to make than liquid nitrogen is.Nitrogen, as a gas is colorless, odorless, and generally considered an inert element.Nitrogen is a naturally occurring element that is essential for growth and reproduction in both plants and animals. It is found in amino acids that make up proteins, in nucleic acids, that comprise the hereditary material and lifes blueprint for all cells, and in many other organic and inorganic compounds. In addition, nitrogen comprises about 80% of the Earth's atmosphere.

Things that contain NitrogenMost foods contain amounts of nitrogen in organic or non-organic form. The highest levels of nitrogen can be found in fruit and veggies like lettuce and spinach. Cured meats like sausage are another source of nitrogen.Elemental nitrogen is found by taking a deep breath; it's almost 80% of our atmosphere. In compounds, nitrogen is found in fertilizers, amino acids, ammonia, and many other substances.Nitrogen compounds are found in foods, organic materials, fertilizers, poisons, and explosives.

IMPORTANCE OF NITROGEN TO LIFENitrogen is important to organisms because it helps the reproduction of plants. Animals get the nitrogen they need by consuming plants or other animals that contain organic molecules composed partially of nitrogen.Nitrogen is a component of amino acids and urea. Amino acids are the building blocks of all proteins. Proteins comprise not only structural components such as muscle, tissue and organs, but also enzymes and hormones essential for the functioning of all living things. Urea is a byproduct of protein digestion. We use the term "organic nitrogen" to describe a nitrogen compound that had its origin in living material. The nitrogen in protein and urea is organic nitrogen. Organic nitrogen can enter septic systems as bodily wastes, discarded food material, or as components of cleaning agents.

English scientist John Mayow was the first to prove that air is not pure oxygen, but rather a cocktail of different gases, one of which is nitrogen. It is one of the world's most ubiquitous elements.yan na lang idagdag mo.
