Geskiendenis
Carl Wilhelm Scheele obtained oxygen by heating mercuric oxide and nitrates in 1771, but did not publish his findings until 1777.
Joseph Priestley also prepared this new air by 1774.
The name oxygen was coined in 1777 by Antoine Lavoisier, whose experiments with oxygen helped to discredit the then-popular phlogiston theory of combustion and corrosion.

Toepassings
Pure oxygen is frequently used to help breathing in patients with respiratory ailments.
Oxygen is used in oxyacetylene welding, as an oxidant for rocket fuel, and in methanol and ethylene oxide production.
It is also used in the production of steel, plastics and textiles.
Plants and animals rely on oxygen for respiration.
