Nitrogen Fact 1 – How Much Nitrogen is in You? It's the most common uncombined (pure) element on Earth. 26. Nitrogen Facts: 1-5 | Discovery and Naming 1. The nitrogen cycle is one of the most important processes in nature for living organisms. It is used widely as an anesthetic in both dental and medical applications. Actually, it is a constituent element of amino acids and therefore of proteins and nucleic acids (DNA and RNA). [2], 6. Leave a Comment. Nitrogen has two stable isotopes: nitrogen-14 and nitrogen-15. Nitrogen is a poor conductor of heat and electricity. Ammonia (N3) a compound of nitrogen is commonly used in fertilizers. The shocking truth is that more than half of this is washed off from fields into rivers leading to pollution.[12]. Nitrogen is not present in air in form of element (represented as N). Interesting Facts about Nitrogen. About 2.5 percent of the weight of living organisms comes from nitrogen in organic molecules. Some soil bacteria can 'fix' nitrogen into a form that plants and animals can use to make amino acids and proteins. Nitrogen is used for packing bags of crisps. Liquid nitrogen is so cold that it can even cause frostbite when it comes in contact with living tissue. Animals get their nitrogen needs met by eating plants or eating animals that eat plants. Nitrogen gas is inert. Nitrogen is found naturally in the body to aid in the creation of amino acids and proteins. Get other interesting facts about liquid nitrogen … It is the lightest member of group 15 of the periodic table. Zygmunt Wróblewski and Karol Olszewski were the Polish physicists who took the credit as the first ones who liquefied nitrogen. The chemist realized that the gas was a part of a chemical compound then called niter, which we now refer to as potassium nitrate. Facts: N has no odor, is tasteless, and colorless. Nitrogen discovery has a very interesting history. It is a colorless, odorless, tasteless gas that is the most plentiful element in Earth’s atmosphere and is a constituent of all living matter. [5], 8. Oxygen bolsters combustion. Due to its volatility, it is a fairly rare element on Earth, remaining as a gas in the atmosphere. The human body is an amazing thing – it consists of many different elements, from oxygen to carbon. Nitrogen Fun Facts: 26-30 | Nitrogen Formation. Atomic Radius (the distance from the centre of the nucleus to the outermost shell of the electron. Nitrogen is atomic number 7, which means each nitrogen atom has 7 protons. Interesting Facts. Nitrogen is nonflammable and does not support combustion. Some of the interesting fact about this element are: Fact 1: Nitrogen is colorless, tasteless, and odorless. Nitrogen is in the air we breathe and in fact, comprises 78.1% of the Earth’s air. [1], 10. There are many steps in the nitrogen cycle including fixation, nitrification, assimilation, ammonification, and denitrification. Nitrogen is commercially produced by the fractional distillation of air. It is the fourth most abundant element in the human body. The human body is an amazing thing – it consists of many different elements, from oxygen to carbon. Nitrogen Fact 1 – How Much Nitrogen is in You? Many of the molecules of life contain nitrogen. [2], 2. Its atomic number is 7 and it is denoted by the symbol ‘N’ in the periodic table. [3], 9. [4], 19. It is thought to be around the seventh most abundant element in the universe by mass. Nitrogen is a fascinating element with many unique properties and uses related to fertilizer, dynamite, medical anesthetic and even car racing. Nitrogen is a chemical element with atomic number seven and atomic weight 14. Comparatively, oxygen comprises approximately 21% of the earth’s atmosphere. [11], 26. It forms negatively charged ions (anions) that readily react with other nonmetals to form covalent bonds. Oklahoma, a state in the U.S., has declared that it will start using nitrogen for all its executions moving forward, thus becoming the first US state to do so. According to some estimate, 120 million tons of synthetic nitrogen is used globally in agriculture each year. Fun Facts About Nitrogen. All Rights Reserved. Did you know that Nitrogen is found is stars, animals, plants and even in our own DNA? Nitrogen is part of many important compounds, such as nitrous oxide, nitroglycerin, nitric acid, and ammonia. Did you know that agricultural activities are responsible for about two-thirds of global nitrogen pollution? The liquid, which has a tremendously low temperature, is elaborated on Facts about Liquid Nitrogen. The nitrogen compound nitroglycerin can be used for relief of angina, a life threatening heart condition. Its element symbol is N. Nitrogen is odorless, tasteless, and colorless gas at room temperature and pressure. [18], 13. Saturn's largest moon, Titan, is the only moon in the solar system with a dense atmosphere.
