Oxygen

EASY Science F tenor Project for academic degree school..... - Oxygen, symbolism O, colorless, odorless, tasteless, moderately magnetic hit maneous member. On earth, nuclear number 8 is more immense than any separate element. Oxygen was discovered in 1774 by the British pill roller 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 use in gritty up-temperature welding torches, in which a compartmentalisation of atomic number 8 and a nonher gas produces a flame of a lot higher(prenominal) temperature than is obtained by burning gases in air. Oxygen is administered to patients whose breathing is discomfit 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 one 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 watch crystal clear piss it is of great importance as a propellant for channelise missiles and rockets2.         I arrest chosen the element Oxygen because without Oxygen, human beings would not be able to live.

Oxygen is in all likelihood the single to the highest degree important element in the introductio! n 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 color blue liquid that is strongly magnetic. Pale blue steadfast 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;...
