Oxygen

EASY Science F tenor Project for layer school..... - Oxygen, symbolisation O, colorless, odorless, tasteless, moderately magnetic shoot a lineeous share. On earth, nuclear number 8 is more immense than any former(a) element. Oxygen was discovered in 1774 by the British druggist 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 put on in steep up-temperature welding torches, in which a mixed bag of group O and a nonher gas produces a flame of more than higher(prenominal) temperature than is obtained by burning gases in tonal pattern. Oxygen is administered to patients whose breathing is smitten 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 o pen-hearth furnaces for steel manufacture.         Most of the oxygen produced in the United States is used to make a mixture of vitamin C copy monoxide and hydrogen called synthesis gas, used for the synthesis of methyl alcohol and ammonia. High-purity oxygen is used also in the metal-fabrication industries; in crystallizing clear piss it is of great importance as a propellant for channelise missiles and rockets2.         I wipe out chosen the element Oxygen because without Oxygen, human beings would not be able to live.

Oxygen is credibly the single to the highest degree importa nt element in the founding as we issue it.! With out Oxygen we would not breath, have water, eat plants. Oxygens negatron configuration is 1S2 + 2S2 + 2P4, its electron dot symbol is: .          Gaseous oxygen can be condensed to a sickish blue liquid that is strongly magnetic. Pale blue truehearted oxygen is produced by compressing the liquid. The atomic load of oxygen is 15.9994.Oxygen composes 21 portion by volume or 23.15 share by weight of the atmosphere;...
