OXYGEN

The oxygen is a chemical element of atomic number 8 and symbol Or.
Traditionally this discovery has been attributed to the chemist Englishman Joseph Priestley (1733-1804), who discovered it in an independent way in 1772, though the first one that published a work on this gas and him gave name he was the chemical Frenchman Lavoisier (1743-1794) in 1777. Did it use for it two Greek ὀξύς (Oxýs) (acid, "literally "sharp", for the flavor of the acids) -γενής (-genes) generator, which it generates "), because he believed that the oxygen was the indispensable constituent one of the acids.
The oxygen is the most abundant third element in the Sun, and plays a role in the cycle of the carbon - nitrogen, a process responsible for the production of stellar energy.
