You are watching: Most common inert gas in the atmosphere
The many abundant gas in the atmosphere is nitrogen. The Earth’s setting is created of roughly 78 percent nitrogen, 21 percent oxygen, 1 percent argon and trace amounts of other gases that encompass carbon dioxide and neon.
Nitrogen is a colorless, unscented and also inert (does no react with various other chemicals) gas. Chemist Daniel Rutherford an initial discovered this chemical facet in 1772. Nitrogen is the most abundant gas in the atmosphere and also the many abundant aspect in the atmosphere.
It"s uncovered in all living organisms. Nitrogen is an essential component of amino acids, protein, DNA and also RNA. Every living organisms count on nitrogen because that growth, metabolic processes and reproduction.
The setting is the primary resource of nitrogen. However, plants and also animals are not able to usage it directly. Nitrogen start the soil v precipitation, pet waste and also dead essential matter. Bacteria in the soil convert the nitrogen into ammonium and also nitrate, which are two forms of nitrogen that can be provided by plants.
Animals then obtain the nitrogen by eating plants and also other animals. Various other bacteria in the floor will transform the ammonium and nitrate into di-nitrogen, bring about nitrogen to it is in released back into the atmosphere. This entire process is well-known as the nitrogen cycle.
Oxygen is the second most numerous gas in the atmosphere and also is the third most abundant aspect in the universe. The was uncovered during two different occasions: by Carl-Wilhelm Scheele in 1771 and also Joseph priesthood in 1774. Oxygen is odorless, colorless and very reactive with other elements.
Oxygen gas (O2) is required by all living organisms for respiration and is a ingredient of DNA molecules. Plants are able to create oxygen and release it earlier into the environment through a procedure known as photosynthesis.
Ozone (O3) is a type of oxygen the is present in the earth atmosphere. Ozone protects the Earth’s surface from ultraviolet radiation through both absorbing and reflecting harmful rays.
Argon is classified together a noble gas and also is colorless, odorless and reasonably inert. Lord Rayleigh and also Sir wilhelm Ramsay an initial discovered argon in 1894. That is the third most abundant gas in the atmosphere, yet it cannot assistance life. Argon is taken into consideration a basic asphyxiant. When inhaled in large amounts, that can cause dizziness, nausea, ns of judgment, suffocation and even death.
Since argon is extremely inert, that is supplied in number of applications such as in incandescent light bulbs, protecting welds indigenous oxidation, insulating gaps in between panes that glass and also as a substitution because that nitrogen as soon as necessary.
Nitrogen, oxygen and argon are the three most abundant facets in the atmosphere, yet there are other vital components the are forced for sustaining life as we know it top top earth.
One that those is carbon dioxide gas. Carbon dioxide provides up 0.04 percent of the Earth"s atmosphere. Do of one atom that carbon bonded to 2 oxygen atom (CO2), carbon dioxide is a an essential component that photosynthesis and other metabolic processes. Without CO2, autotrophs prefer plants and photosynthetic bacteria wouldn"t have the ability to turn solar energy into usable chemical energy via photosynthesis. This would typical there would certainly be no method for power to get in earth"s ecosystems, i beg your pardon would result in the demise of life top top earth.

Water, H2O, is an additional necessary molecule for life. Girlfriend can uncover it in its vapor type in the atmosphere.
