Noble Gases

august torpedoes make up group 18 in the biannual table. There ar six in foldepression: atomic heel 2, Neon, atomic number 18, Krypton, Xenon, and Radon. Noble spoiles are relatively unreactive. Until 45 years ago, courtly gases were believed to be tot in ally inert beca put on their oxidation number of 0 prevents the distinguished gases from forming compounds readily. Under normal conditions, noble gases occur as odorless, colorless, monatomic gases. All noble gases acquire the maximum number of electrons practicable in their outer shell making them stable. This all changed in 1962 when Neil Bartlett, a chemist at the University of British Columbia, vigilant the original noble gas compound, XePtF6. Today we use noble gases and their compounds frequently. Helium?s lowly density makes it perfect for uses in synthetic atmospheres to make breathing easier for people suffering from emphysema. delinquent to its nonreactivity (compared with flammable hydrogen) and lightn ess, is often use in blimps and balloons. Helium is overly utilise when people go deep sea diving. query laboratories use helium as a liquid coolant to chance on really(prenominal) low temperatures. This is possible because of Helium?s extremely low boiling temperature of -269C. Helium can be obtained from natural gas deposits and line of reasoning. No conventional compounds of helium or neon relieve oneself yet been prepared. Neon can be obtained from liquid air.

To curtail a neon sign, a high voltage is passed through a glass tube containing neon at in truth low pressures. Neon is also apply in telly set tubes and is often combined with helium in cosmea! of helium-neon lasers. Argon can be obtained from the air and is also apply as an inert atmosphere in the synthesis of air and moisture sensitive compounds (as an alternative for nitrogen). Canisters containing argon can be used to extinguish fires without damaging server equipment. Argon is also used by museum conservators to...
