    • n oxygen Chemical symbol, O; atomic weight, 16. An element discovered by Priestley in 1774, who called it dephlogisticated air. It was finally called oxygen by Lavoisier, because supposed to be present in all acids. Further investigation, however, has proved that this is not the case. Oxygen is a chemical element existing as a permanent gas, colorless, odorless, and tasteless, and somewhat heavier than atmospheric air. It is soluble in water, which at a temperature of 60° F. dissolves of its volume of oxygen. Oxygen combines very readily with most of the elements, and forms oxids with all of them excepting fluorin. The act of combination is so energetic in many cases as to evolve light and heat, the phenomena of combustion. In other cases, as in the tarnishing or rusting of metals and the decay of animal or vegetable substances, oxidation takes place so slowly that, while the result is the same, the heat evolved at one time is not enough to produce luminous effects or even to be sensible. Free or uncombined oxygen is essential to all animal and vegetable life. Animal heat and muscular energy are results of a slow combustion produced in all parts of the system by oxygen carried in the blood from the lungs. In sunlight oxygen is exhaled by growing plants, but a certain quantity is assimilated and is essential to life. Oxygen is the most widely distributed and abundant element in nature; it constitutes about one fifth of the total volume of the atmosphere, which is a mechanical mixture of oxygen and nitrogen. Water contains about 89 per cent. of it by weight, and it is found in most animal and vegetable products, acids, oxids, and salts. The rocks which make up most of the earth's crust contain between 40 and 50 per cent. of oxygen. Under certain conditions oxygen may be made to pass into an allotropic or condensed form called ozone.

  • Interesting fact: If a substance is burned and all of the results of its burning (smoke, ash, soot and gas) are captured and weighed, they will be a little heavier than the original substance because they have been combined with oxygen.
