CAS Naj Npawb 7439-90-9 txheeb xyuas Krypton, cov roj zoo uas paub txog nws cov khoom tshwj xeeb thiab ntau daim ntawv thov tshwj xeeb. Nov yog cov yam ntxwv tseem ceeb thiab cov ntsiab lus ntawm Krypton:
Chemical Cim: Kr
Lub cev muaj zog:
Cov tsos mob: Krypton yog qhov tsis muaj ntxhiab, tsis muaj xim, tsis muaj roj nyob hauv chav tsev kub thiab tus qauv siab.
Atomic Number: 36
Atomic huab hwm coj: 83.798 u (unified atomic mass units)
Boiling Point: -153.4 ° C (-244.1 ° F) ntawm 1 atm
Melting Point: -157.4 ° C (-251.3 ° F) ntawm 1 atm
Ceev: Txog 3.75 npaug hnyav dua huab cua ntawm STP (Standard Temperature and Pressure)
Chemical Properties:
Tsis-Reactivity: Ua cov roj noble, Krypton yog qhov tsis zoo heev thiab tsis tuaj yeem tsim cov tebchaw hauv ib txwm muaj.
Stability: Tshwj xeeb ruaj khov vim nws ua tiav electron plhaub.
Kev siv thiab kev siv:
Teeb pom kev zoo: Krypton yog siv nyob rau hauv qee hom kev siv teeb pom kev zoo, suav nrog cov duab thaij duab thiab cov teeb pom kev tshwj xeeb zoo li cov siv hauv lighthouses thiab tshav dav hlau khiav teeb, vim nws lub peev xwm los tawm lub teeb ci dawb thaum zoo siab hluav taws xob.
Lasers: Krypton lasers yog ua hauj lwm nyob rau hauv ntau yam kev siv xws li laser phais, spectroscopy, thiab holography.
Vuam: Sib xyaw nrog argon, nws yog siv los ua cov roj tiv thaiv hauv qee hom vuam los tiv thaiv thaj chaw vuam los ntawm huab cua paug.
Radiometry thiab Photometry: Ua haujlwm raws li tus qauv siv rau calibration ntawm cov khoom ntsuas no.
Leak Detection: Vim nws qhov hnyav molecular hnyav thiab tsis muaj toxicity, krypton yog siv los ua cov roj tracer rau kev kuaj xyuas cov xau hauv cov kaw lus kaw.
Cov yam ntxwv tshwj xeeb:
Tsis tshua muaj: Krypton yog ib qho tsis tshua muaj roj pom muaj nyob hauv cov kab hauv ntiaj teb huab cua (kwv yees li 1 feem ntawm ib lab los ntawm ntim).
Monatomic: Raws li tus qauv qauv, krypton tshwm sim raws li tus neeg atoms ntau dua li cov molecules.
