It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. After hydrogen and helium, oxygen is the third-most abundant element in the universe by mass. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O. Diatomic oxygen gas currently constitutes 20.95% of the Earth's atmosphere, though this has changed considerably over long periods of time. Oxygen makes up almost half of the Earth's crust in the form of oxides.</skos:definition> <skos:inScheme rdf:resource="https://w3id.org/ozcar-theia/"/> <skos:exactMatch rdf:resource="http://www.eionet.europa.eu/gemet/concept/5982"/> <skos:exactMatch rdf:resource="http://vocabs.lter-europe.net/EnvThes/20850"/> <skos:broader rdf:resource="https://w3id.org/ozcar-theia/c_c2c513c5"/> <skos:altLabel xml:lang="en">O</skos:altLabel> <skos:narrower rdf:resource="https://w3id.org/ozcar-theia/c_9a042f66"/> <skos:narrower rdf:resource="https://w3id.org/ozcar-theia/c_7603f572"/> <dct:created rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2022-02-07T17:00:00</dct:created> </owl:NamedIndividual> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_2b4d3db8"> <ns1:constrains> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_a54bce82"> <metadata_def:mappingSameURI rdf:resource="https://w3id.org/ozcar-theia/c_a54bce82"/> </rdf:Description> </ns1:constrains> </rdf:Description> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_2d1460f4"> <ns1:hasObjectOfInterest rdf:resource="https://w3id.org/ozcar-theia/c_a54bce82"/> </rdf:Description> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_38edd906"> <ns1:hasObjectOfInterest rdf:resource="https://w3id.org/ozcar-theia/c_a54bce82"/> </rdf:Description> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_62298559"> <ns1:hasObjectOfInterest rdf:resource="https://w3id.org/ozcar-theia/c_a54bce82"/> </rdf:Description> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_7603f572"> <skos:broader rdf:resource="https://w3id.org/ozcar-theia/c_a54bce82"/> </rdf:Description> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_9a042f66"> <skos:broader rdf:resource="https://w3id.org/ozcar-theia/c_a54bce82"/> </rdf:Description> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_c2c513c5"> <skos:narrower rdf:resource="https://w3id.org/ozcar-theia/c_a54bce82"/> </rdf:Description> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_c3a5d6fd"> <ns1:hasObjectOfInterest rdf:resource="https://w3id.org/ozcar-theia/c_a54bce82"/> </rdf:Description> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_c6d197a2"> <ns1:hasObjectOfInterest rdf:resource="https://w3id.org/ozcar-theia/c_a54bce82"/> </rdf:Description> <rdf:Description rdf:about="https://w3id.org/ozcar-theia/c_cff4f625"> <ns1:hasObjectOfInterest rdf:resource="https://w3id.org/ozcar-theia/c_a54bce82"/> </rdf:Description> </rdf:RDF>
