atomic number 8,O,oxygen- a nonmetallic bivalent element that is normally a colorless odorless tasteless nonflammable diatomic gas; constitutes 21 percent of the atmosphere by volume; the most abundant element in the earth's crust gas- a fluid in the gaseous state having neither independent shape...
An atom’s valence is its ability to combine. An element’s valency expresses the number of bonds that an atom can form as a component of a compound. Oxygen has an electron count of eight. As a result, the electronic configuration of oxygen is 2,6. ...
The compound broke down, producing liquid mercury metal and a gas: When Priestley tested the new gas, he found the same properties that Scheele had described. Priestley even tried breathing the new gas he had produced. His description of that experience has now become famous: Antoine-...

Elemental oxygen also reacts with some compounds. If it is possible to oxidize any of the elements in a given compound, further oxidation by oxygen can occur. For example, hydrogen sulfide, H2S, contains sulfur with an oxidation state of 2-. Because the sulfur does not exhibit...

and metallic. Oxygen supports combustion, combines with most elements, and is a component of hundreds of thousands of organic compounds. Ozone (O3), a highly active compound with a name derived from the Greek word for 'I smell', is formed by the action of an electrical discharge or ultravio...
The vapourised element, e.g. Mercury passes out of the diffuser into a quartz tube containing a gold mesh (33) with which it forms an amalgam. The amalgam is heated by induction (34), after the Oxygen supply has been cut off and the appts. has been purged with Argon (12), within...
Verb1.oxygenise- change (a compound) by increasing the proportion of the electronegative part; or change (an element or ion) from a lower to a higher positive valence: remove one or more electrons from (an atom, ion, or molecule)
