Noble Gases

august torpedoes make up group 18 in the biannual table. There ar six in essence: atomic fare 2, Neon, atomic number 18, Krypton, Xenon, and Radon. Noble flatulencyes are relatively unreactive. Until 45 years ago, courtly gases were believed to be but inert beca put on their oxidation number of 0 prevents the master 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 ein truth changed in 1962 when Neil Bartlett, a chemist at the University of British Columbia, hustling the original noble gas compound, XePtF6. Today we use noble gases and their compounds frequently. Helium?s offsetly density makes it perfect for uses in synthetic atmospheres to make breathing easier for people suffering from emphysema. collect to its nonreactivity (compared with flammable hydrogen) and lightness, is o ften use in blimps and balloons. Helium is besides utilise when people go deep sea diving. enquiry laboratories use helium as a liquid coolant to extend to 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 aura. No conventional compounds of helium or neon find yet been prepared. Neon can be obtained from liquid air.

To keep a neon sign, a high voltage is passed make a glass tube containing neon at very low pressures. Neon is as well as apply in telecasting set tubes and is often combined with helium in incep tion of helium-neon lasers. Argon can be obt! ained from the air and is also employ 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...
