Noble Gases

august torpedoes make up group 18 in the biannual table. There are six in tot: atomic turning 2, Neon, atomic number 18, Krypton, Xenon, and Radon. Noble bollix upes are relatively unreactive. Until 45 years ago, courtly gases were believed to be completely inert beca put on their oxidation number of 0 prevents the direful 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 solely changed in 1962 when Neil Bartlett, a chemist at the University of British Columbia, lively the original noble gas compound, XePtF6. Today we use noble gases and their compounds frequently. Helium?s subalternly density makes it perfect for uses in synthetic atmospheres to make breathing easier for people suffering from emphysema. due to its nonreactivity (compared with flammable hydrogen) and lightness, is often use in blimps and balloons. Helium is in any case utilise when people go deep sea diving. interrogation 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 get off. No conventional compounds of helium or neon begin yet been prepared. Neon can be obtained from liquid air. To uphold a neon sign, a high voltage is passed through a glass tube containing neon at rattling low pressures. Neon is in any case apply in television set set tubes and is often combined with helium in intro of helium-neon lasers. Argon can be obtained from the air and is also utilize 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 c onservators to... !
