Nitrogen atmosphere
Webb13 apr. 2024 · Nitrogen is essential for life as a fundamental unit of nucleic acids and proteins. However, the largest reservoir of nitrogen, in the form of atmospheric N2, is not available to be used as a nitrogen source for most life, outside of a small amount of nitrogen which is dissociated by high energy phenomena. Webb5 juli 2013 · The partial oxidation of organic matter in the atmosphere generally adds polar oxygenated or nitrogenous functional groups (e.g. ketones or alcohol groups), which tend to make the products of oxidation less volatile and more water soluble, and hence more likely to transfer from the gas to aerosol phase [ 3 ].

As of 2024, by mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. [8] Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Visa mer The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere.
