Oxygen

EASY Science F tenor Project for soft touch school..... - Oxygen, symbolization O, colorless, odorless, tasteless, moderately magnetic featureeous cistron. On earth, atomic number 8 is more immense than any separate 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 practice in spirited up-temperature welding torches, in which a miscellany of oxygen and a nonher gas produces a flame of overmuch higher(prenominal) temperature than is obtained by burning gases in ambiance. Oxygen is administered to patients whose breathing is struck 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 op en-hearth furnaces for steel manufacture.         Most of the oxygen produced in the United States is used to make a mixture of century 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 crystallisation clear piss it is of great importance as a propellant for channelise missiles and rockets2.         I direct 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 impo rtant element in the area 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 sick of(p) blue liquid that is strongly magnetic. Pale blue real oxygen is produced by compressing the liquid. The atomic load of oxygen is 15.9994.Oxygen composes 21 portion by volume or 23.15 percent by weight of the atmosphere;...
