Oxygen

EASY Science F tenor Project for distinguish school..... - Oxygen, symbolism O, colorless, odorless, tasteless, moderately magnetic heavy weaponeous component. On earth, nuclear number 8 is more immense than any former(a) element. Oxygen was discovered in 1774 by the British apothecary Joseph Priestley and, independently, by the Swedish chemist Carl Wilhelm Scheele; it was shown to be an elemental gas by the French chemist Antoine Laurent Lavoisier in his classic experiments on combustion.         Large amounts of atomic number 8 are go for in senior high up-temperature welding torches, in which a multifariousness of atomic number 8 and a nonher gas produces a flame of a good deal higher(prenominal) temperature than is obtained by burning gases in communicate. Oxygen is administered to patients whose breathing is laid low(p) and also to people in aircraft flying at high altitudes, where the poor oxygen concentration cannot support normal respiration. Oxygen-enriched air is used in open-hearth furnaces for steel manufacture.         Most of the oxygen produced in the United States is used to make a mixture of nose candy copy monoxide and hydrogen called synthesis gas, used for the synthesis of wood spirit and ammonia. High-purity oxygen is used also in the metal-fabrication industries; in vitreous silica clear piss it is of great importance as a propellant for channelise missiles and rockets2.         I film chosen the element Oxygen because without Oxygen, human beings would not be able to live.

Oxygen is plausibly the single to the highest degree important element in the globe as we issue it. Wi th out Oxygen we would not breath, have wate! r, eat plants. Oxygens negatron configuration is 1S2 + 2S2 + 2P4, its electron dot symbol is: .          Gaseous oxygen can be condensed to a parboil blue liquid that is strongly magnetic. Pale blue steady oxygen is produced by compressing the liquid. The atomic load of oxygen is 15.9994.Oxygen composes 21 portion by volume or 23.15 per centum by weight of the atmosphere;...
