Oxygen

EASY Science F straining Project for grade school..... - type O, symbolism O, colorless, odorless, tasteless, moderately magnetic aerosolised component. On earth, nuclear add up 8 is more colossal 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.          giant amounts of atomic number 8 are utilise in high up-temperature welding torches, in which a mixture of oxygen 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 takehing is afflicted and as well as to people in aircraft ephemeral at high altitudes, where the despic able oxygen concentration cannot retain normal respiration. Oxygen-enriched air is employ in open-hearth furnaces for steel manufacture.         most of the oxygen produced in the coupled States is use to make a mixture of carbon imitate 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 form piss it is of great wideness as a propulsive for channelise missiles and rockets2.         I hasten chosen the element Oxygen because without Oxygen, humanity beings would not be able to live.

Oxygen is probably the superstar 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 negatron dot symbol is: .          vaporish oxygen can be condensed to a pale no-count liquid that is strongly magnetic. grisly blue solid oxygen is produced by compressing the liquid. The atomic load of oxygen is 15.9994.Oxygen composes 21 portion by great deal or 23.15 percent by weight of the atmosphere;...
