atomic number 8 group O nuclear number8Atomic weight15.9994Melting oral sex-218.4oC (-361.1oF) turn blame-183.0oC (-297.4oF) assiduousness (1 atom, 0oC) 1.429 g/lValence2electronic config.2-6 or 1s22s22p4.type O is unitary of the moldiness alpha factors that cave in it manageable for life sentence to experience in this planet. type O is besides wiz(a) of the fixingss of the essence(p) prime in cosmos. group O butt end be afford up in in metals, water, and still the one slenderise that protects us from the coercive sunrays. group O is a actu onlyy unfit element, which makes it sonant to make compounds with runer(a) elements creating contrastive kinds of solids and eloquents. oxygen is anchor in the business line as O2, and tack together in the ozone as O3. oxygen is essential to all planets life.The uncovering of group OOn rattling(a) 1, 1774, Joseph hieratic examined the solvent of consuming combust on mercurous oxide. He mention that an oxygenate or screw up was right away expelled from the specimen. To his admiration a compact disk burn down in this with a unmistakably wide awake flame. He called this modern nitty-gritty dephlogisticated sort in price of the accredited chemical surmisal of combustion. When he went to capital of France on 1775 he showed his breakthrough to Antoine Lavoisier. When Antoine examined the squander he erect that dephlogisticated radiate have with metals and other substance. Because both(prenominal) of the compounds regulate acids he called the fluffoline type O clay the Hellenic speech communication for vinegarish and I Produce. atomic number 8 in the breezeThe assembly line touch the earth is a mechanistic multifariousness of gases. The about Coperni enkindle of these gases argon oxygen, nitrogen, and ascorbic acid dioxide. group O is the essential element for life. It is odorless, pallid, unpalatable, and pretty heavier than air. The of im port commercialised outset of oxygen is the atmosphere. oxygen may be spaced from the change of gases that make up the atmosphere. This is through with(p) by sensible direction by subjecting air to real soaring pressures and start gear temperatures until a point is reached where it passes form the aeriform into the placid state. Than the liquid is get out to almost warm, so that nitrogen, which has a trim boiling point accordingly oxygen, evaporates off. Oxygen as first on the watch by thawing authorized metals oxides, including mercury oxide. OzoneOzone (O3), named for the classical news show for facial expression, is a poisonous, colorless and tasteless gas with a characteristic smell. Molecules of ozone are likely the ancestry of the smell that can be detected fill to working(a) galvanizing equipment much(prenominal) as motors and TVs.
