Oxygen

Oxygen and its compounds play a key role in legion(predicate) of the important processes of life and industry. Oxygen in the biosphere is essential in the processes of respiration and metabolism, the look ons by which animals derive the energy collect to sustain life. Furthermore, type O is the nearly abundant piece at the surface of the Earth. In combined form it is found in ores, earths, rocks, and gemstones, as well as in all aid organisms. Oxygen is a gaseous chemical element in group VA of the periodic table. The chemical symbol for nuclear type O is O, its atomic number is 8, and its atomic weight is 15.9994. Elemental type O is cognise principally in the gaseous form as the diatomic molecule, which makes up 20.95% of the volume of dry air. Diatomic oxygen is colorless, odorless, and tasteless. Two 18th-century scientists tract the credit for initial isolating uncomplicated oxygen: Joseph PRIESTLEY (1733-1804), an incline clergyman who was employed as a literary coadjutor to Lord Shelburne at the time of his most significant observational work, and Carl Wilhelm SCHEELE (1742-86), a Swedish pharmacist and chemist. It is for the most part believed that Scheele was the first to keep apart oxygen, but that Priestley, who independently achieved the isolation of oxygen somewhat later, was the first to publicly announce his findings. The exposition of the findings of Priestley and the resultant clarification of the record of oxygen as an element was accomplished by the cut scientist Antoine-Laurent LAVOISIER (1743-94). Lavoisiers experimental work, which extended and improve upon Priestleys experiments, was principally responsible for the perceptiveness of COMBUSTION and the establishment of the natural law of conservation of matter. Lavoisier gave oxygen its name, which is derived from ii Greek words that mean acid former. Lavoisier held the mistaken idea that oxides, when fade away in water, would form...
