Background Oxygen is one of the basic chemical elements. In its most common form, oxygen is a colorless gas found in air. It is one of the life-sustaining elements on Earth and is needed by all animals. Oxygen is also used in many industrial, commercial, medical, and scientific applications. It is used in blast furnaces to make steel, and is an important component in the production of many synthetic chemicals, including ammonia, alcohols, and various plastics. Oxygen and acetylene are combusted together to provide the very high temperatures needed for welding and metal cutting. Oxygen is one of the most abundant chemical elements on Earth. In 1895, Karl Paul Gottfried von Linde of Germany and William Hampson of England independently developed a process for lowering the temperature of air until it liquefied.

In 1901, compressed oxygen gas was burned with acetylene gas in the first demonstration of oxy-acetylene welding. Raw Mcatericals The Manufacturing Process Pretreating Nancy EV Bryk. Oxygen.

Watch steel melt when charcoal (carbon) burns in liquid oxygen. Discovery of Oxygen Dr. Oxygen was discovered in 1774 by Joseph Priestley in England and two years earlier, but unpublished, by Carl W.

Scheele heated several compounds including potassium nitrate, manganese oxide, and mercury oxide and found they released a gas which enhanced combustion. Interesting Facts about Oxygen Liquid oxygen is pale blue and paramagnetic. References. Oxygen - Element information, properties and uses | Periodic Table. (Promo) You're listening to Chemistry in its element brought to you by Chemistry World, the magazine of the Royal Society of Chemistry. (End promo) Chris Smith Hello! And welcome to Chemistry in its element, where we take a look at the stories behind the elements that make up the world around us. I'm Chris Smith. Mark Peplow Little did those humble Cyanobacteria realize what they were doing when two and a half billion years ago, they started to build up their own reserves of energy-rich chemicals, by combining water and Carbon dioxide.

So who first noticed this ubiquitous stuff? Oxygen isn't only about the Dioxygen molecules that sustain us. So why life is a gas, that was Mark Peplow revealing the secrets of the element that we can't live without. Johnny Ball Today one gram can be beaten into a square meter sheet just 230 atoms thick, one cubic centimetre would make a sheet 18 square meters, 1gm could be drawn out to make 165 meters of wire just 1/200th of a millimetre thick.

It's a good thing that oxygen makes up over twenty percent of the Earth's atmosphere. We are the only planet in the solar system with enough oxygen gas available to let us survive. Did you know that if you breathe too much oxygen you could die? What about this: If you have a room filled with oxygen and hydrogen (H) and someone lights a match... it will explode! That's because oxygen is very reactive. Oxygen is the eighth element of the periodic table and can be found in the second row (period). Oxygen Facts - Periodic Table of the Chemical Elements.

Isotopes: Nine isotopes of oxygen are known. Properties: Oxygen gas is colorless, odorless, and tasteless. Uses: Oxygen was the atomic weight standard of comparison for the other elements until 1961 when the International Union of Pure and Applied Chemistry adopted carbon 12 as the new basis.

Oxygen. Oxygen (O) is a chemical element. In nature, oxygen is a gas with no color or smell. Oxygen is a very important element because it is a part of the air people breathe and the water people drink. Because of this, oxygen supports life. Many living things (including humans) need oxygen to live and breathe, though it is poisonous to some forms of life. In liquid state of matter, oxygen is blue.[1][2][3] Discovery of oxygen[change | edit source] Oxygen was initially discovered in 1772 by Carl Wilhelm Scheele. Oxygen in nature[change | edit source] A drop of water. Water contains oxygen. Air also contains oxygen. Combustion of wood in a match. Uses of oxygen[change | edit source] Oxygen is also what makes burning possible. Oxygen can be used in smelting metal from ore. Oxygen is used in hospitals for killing bacteria. Oxygen is used in water treatment to purify the water to make it safe for us to drink. Production of gas[change | edit source] Pure oxygen can be produced in several ways.

Oxygen. Blue white glow from an oxygen discharge tube. Oxygen is an important part of the atmosphere, and is necessary to sustain most terrestrial life as it is used in respiration. However, it is too chemically reactive to remain a free element in Earth's atmosphere without being continuously replenished by the photosynthetic action of living organisms, which use the energy of sunlight to produce elemental oxygen from water.

Another form (allotrope) of oxygen, ozone (O 3), strongly absorbs UVB radiation and consequently the high-altitude ozone layer helps protect the biosphere from ultraviolet radiation, but is a pollutant near the surface where it is a by-product of smog. At even higher low earth orbit altitudes, atomic oxygen is a significant presence and a cause of erosion for spacecraft.[7] Oxygen is produced industrially by fractional distillation of liquefied air, use of zeolites with pressure-cycling to concentrate oxygen from air, electrolysis of water and other means.

Say what? History and Uses: Oxygen had been produced by several chemists prior to its discovery in 1774, but they failed to recognize it as a distinct element. Oxygen is the third most abundant element in the universe and makes up nearly 21% of the earth's atmosphere. Oxygen is a highly reactive element and is capable of combining with most other elements.
