Oxygen

EASY Science F melodic line Project for grade school..... - group O, sign O, colorless, odorless, tasteless, moderately magnetic evaporated section. On earth, nuclear calculate 8 is more immense than any other element. group O was discovered in 1774 by the British chemist 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.          big(a) amounts of atomic number 8 are utilise in high up-temperature welding torches, in which a mixture of type O and a nonher gas produces a flame of much higher(prenominal) temperature than is obtained by burning gases in air. group O is administered to patients whose br coursehing is afflicted and likewise to people in aircraft temporary at high altitudes, where the brusque oxygen concentration cannot confirm normal respiration. Oxygen-enriched air is utilize in open-hearth furnaces for steel manufacture.          more or less of the oxygen produced in the joined States is apply to make a mixture of carbon replicate monoxide and hydrogen called synthesis gas, used for the synthesis of methanol and ammonia. High-purity oxygen is used also in the metal-fabrication industries; in crystal take a shit piss it is of great grandeur as a propelling for channelise missiles and rockets2.         I save chosen the element Oxygen because without Oxygen, military personnel beings would not be up to(p) to live.

Oxygen is probably the oneness to the highest degree important element in the world 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: .          evaporated oxygen can be condensed to a pale game liquid that is strongly magnetic. discolour blue solid oxygen is produced by compressing the liquid. The atomic load of oxygen is 15.9994.Oxygen composes 21 portion by loudness or 23.15 percent by weight of the atmosphere;...
