I gas esisinda. Yokufakela gas radon: iimpawu, iimpawu, isiqingatha-ubomi

Gas - enye kwiimo udibaniso ukwimo. Imimoya ngoku emoyeni, hayi kuphela Emhlabeni, kodwa emajukujukwini. Bona ezinxulumene olulula, hexa weightlessness. I elula hydrogen. Yaye yintoni na igesi esinzima? Makhe sibone oko.

Irhasi esisinda

Igama elithi "umoya" lisuka kwigama lesiGrike elithi 'udushe. " amasuntswana zayo mobile eziyelelene lathamba omnye nomnye. Zihamba ngokwazo, ndibazalisa ngokunxila bonke indawo efumanekayo. Irhasi inokuba into elula kwaye ziqulathe atom kwento enye kwaye inokuba ambaxa eziliqela.

Irhasi elula enzima (bushushu) na radon, zayo izinyo mass 222 g / Mol. Yena radioactive yaye enemibala ngokupheleleyo. Emva kokuba kucingwa ukuba xenon kunawo, kukho ubunzima atom ka-131 g / Mol. Irhasi enzima ezisele iikhompawundi.

Phakathi khompawundi zondle ze gesi esisinda kubushushu ka-20 ^{° C} yi Tungsten fluoride (VI). ubunzima bayo izinyo yi 297,84 g / igala, kwaye mninzi - 12.9 g / l. Phantsi kweemeko eziqhelekileyo, kuba irhasi enemibala emihle, etshaya, yaye blue umoya ofumileyo. Tungsten hexafluoride iyasebenza kakhulu, khona ngokulula iguqulelwa ulwelo xa zokupholisa.

radon

Ukuvulwa gas yenzekile ngexesha yokufunda ukufunda yemisebe. Ngexesha sokonakalisa kwezinye izinto, izazinzulu ziye ngokuphindaphindiweyo wabonisa into ethile asebenza kunye namanye amasuntswana. URutherford wayibiza emanation.

Ngaloo kwafunyaniswa ukuba emanation thorium - Thoron, Radium - radon, actinium - actinon. Kamva kwafunyaniswa ukuba zonke ezi emanations ezi izinto ezineeathom ezilinganayo leyo nto - yegesi egalelwe. Robert Grey Uilyam Ramzay okokuqala kwayo ifomu yayo enyulu yaye wenza imilinganiselo yayo.

Etafileni periodic radon yeyona nto eqela 18 zenani 86. Ku ibekwe phakathi eFransi astatine. Phantsi kweemeko eziqhelekileyo, iyeza yigesi, akukho incasa, ivumba kunye nombala.

NeGesi amaxesha 7.5 luthe komoya. It enyibilikayo emanzini ulunge ngaphezu kwezinye iigesi amanene. Le pende, eli nani linganyuka. Kuzo zonke iigesi ezinqabileyo Nguye kunazo esebenzayo, Ngokusebenza lula fluorine neoksijini.

Igesi radioactive radon

Enye iimpawu element - yemisebe. Isiqalelo iye izinto ezineeathom ezilinganayo ezingamashumi amane ukuphumla yendalo - ngumntu. Bonke bephela iyahlozinga futhi bewenza ukubola eqhumayo. Isiqingatha-ubomi of radon, ngakumbi ngqo, Isotope iyizinzise, ziintsuku 3.8.

Ngenxa igesi radioactive kakhulu iye fluorescence. Le into sukube kwaye ulwelo kubalasele oluhlaza. Le radon okuqinileyo itshintsha mbala wayo ukusuka mthubi ukuya ebomvu xa zipholile kumaqondo nitrogen - malunga -160 ° ^C.

Radon kuba ayityhefu kakhulu emntwini. Iimveliso enzima non-aziphethe ezifana ಪೇನ್ ipheyini, ilothe, bismuth evela ekungafuneki yayo. Bona ke kakubi kakhulu salawo aphumayo. Ekuphuculeni eba ezi zinto ityhefu umzimba. Emva ukutshaya, radon ngoyena nobangela wesibini ziqhelekileyo zomhlaza wemiphunga.

Indawo nokusetyenziswa radon

Irhasi esisinda yenye ezinqabileyo izinto zomhlaba uthinte. Kwindalo, radon yinxalenye ores eziqulathe neyuranium-238, thorium-232, neyuranium-235. Xa ekonakaleni kwabo kukhululwa kuyo, oluwe emoyeni kunye kwehayidrosfere bomhlaba.

Radon oluhlala emlanjeni kunye amanzi olwandle, izityalo kunye lomhlaba izinto zokwakha. Xa umoya, umxholo wayo kwandisa komhlaba kunye nomsebenzi mlilo, ukuba nezokukhupha i phosphate kunye nezityalo okuvela namandla.

Ngoncedo le gesi iziphene ziitectonic plates, iidiphozithi of thorium neyuranium. Isetyenziswa kwezolimo ukuze isebenze izilo feed. Radon isetyenziswa yokunyibilikisa isinyithi, izifundo lobungakananai aphantsi komhlaba, amayeza ethandwayo iibhate radon.
