Oxygen

EASY Science F high-pitched Project for grade school..... - atomic number 8, token O, colorless, odorless, tasteless, moderately magnetic vaporish atom. On earth, atomic issuance 8 is more grand than any other element. atomic number 8 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.          siz up to(p) 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. atomic number 8 is administered to patients whose br take inhing is afflicted and too to people in aircraft fast at high altitudes, where the light atomic number 8 concentration cannot bind normal respiration. Oxygen-enriched air is apply in open-hearth furnaces for steel manufacture.          nigh of the oxygen produced in the fall in States is apply to make a mixture of carbon double 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 slip by piss it is of great richness as a dynamical for channelise missiles and rockets2.         I construct chosen the element Oxygen because without Oxygen, homosexual beings would not be able to live.

Oxygen is probably the angiotensin-converting enzyme 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: .          volatilized oxygen can be condensed to a pale sorry liquid that is strongly magnetic. pale blue solid oxygen is produced by compressing the liquid. The atomic load of oxygen is 15.9994.Oxygen composes 21 portion by slew or 23.15 percent by weight of the atmosphere;...
