Yuav luag tag nrho cov argon Nyob rau hauv lub ntiaj teb huab cua yog radiogenic argon -40, muab tau los ntawm kev lwj ntawm poov tshuaj-40 nyob rau hauv lub ntiaj teb crust. Hauv ntiaj teb, argon -36 yog tam sim no Feem ntau argon isotope , raws li nws yog feem ntau yooj yim tsim los ntawm stellar nucleosynthesis hauv supernovas.
Tsis tas li ntawd, qhov twg argon isotope muaj ntau tshaj plaws hauv qhov xwm txheej?
Hauv ntiaj teb, feem coob ntawm argon yog cov argon ntawm isotope -40, uas tshwm sim los ntawm radioactive decay ntawm poov tshuaj-40, raws li Chemicool. Tab sis nyob rau hauv qhov chaw, argon yog tsim nyob rau hauv cov hnub qub, thaum ob hydrogen nuclei, los yog alpha-particles, fuse nrog silicon-32. Qhov tshwm sim yog qhov argon ntawm isotope -36.
Ib yam li ntawd, qhov twg argon 3 isotopes muaj ntau tshaj? Qhov twg ntawm argon peb lub isotopes yog ntau tshaj: argon-36 argon-38, lossis argon-40? (Pib qhia: atomic loj ntawm argon yog 39.948 amu.)
Ib tug kuj yuav nug, uas isotope yog qhov ntau tshaj?
Ntawm peb hydrogen isotopes , H-1 yog ze tshaj nyob rau hauv huab hwm coj mus rau qhov hnyav nruab nrab; yog li ntawd, nws yog tus ntau tshaj.
Dab tsi yog cov isotopes ntawm argon?
Argon (18 Ar ) muaj 26 paub isotopes , los ntawm 29 Ar rau 54 Ar thiab 1 isomer (32m ua Ar ), ntawm peb qhov ruaj khov (36 Ar , 38 Ar , thiab 40 Ar ). Nyob ntiaj teb, 40 Ar ua 99.6% natural argon.
