Muaj peb lub isotopes ntawm carbon pom nyob rau hauv qhov - carbon-12 , carbon-13 , thiab carbon-14. Tag nrho peb muaj rau protons, tab sis lawv cov lej neutron - 6, 7, thiab 8, raws li - txhua qhov sib txawv.
Yog li ntawd, peb cov isotopes feem ntau yog cov carbon?
Ntuj isotopes Muaj peb yam tshwm sim isotopes ntawm carbon: 12 , 13, 14 ib.
Ib yam li ntawd, dab tsi yog ib qho isotope feem ntau? Cov feem ntau carbon isotope yog carbon-12. Nws lub npe qhia tias nws cov nucleus muaj rau protons thiab rau neutrons, rau tag nrho ntawm 12. Nyob rau lub ntiaj teb, carbon-12 suav txog yuav luag 99 feem pua ntawm cov pa roj carbon monoxide. Cov kws tshawb fawb siv atomic mass units, lossis amu, los ntsuas qhov loj ntawm cov ntsiab lus.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog ob qho isotopes feem ntau ntawm carbon?
Isotopes ntawm Carbon Txog tam sim no feem ntau isotope ntawm carbon yog carbon-12 (12C), uas muaj rau neutrons ntxiv rau nws rau 6 protons. Tom ntej no heavyest carbon isotope, carbon-13 (13C), muaj xya neutrons. Ob leeg 12C thiab 13C yog hu ua cov isotopes ruaj khov vim lawv tsis lwj mus rau lwm cov ntaub ntawv lossis cov ntsiab lus dhau sijhawm.
Dab tsi yog cov isotopes ntawm carbon siv rau?
Cov pa roj carbon : isotope cov ntaub ntawv. Cov pa roj carbon isotopes thiab feem ntau C-13 yog siv nyob rau hauv ntau yam kev siv sib txawv. C-13 yog siv rau Piv txwv li hauv cov organic chemistry kev tshawb fawb, kev tshawb fawb rau hauv cov qauv molecular, cov metabolism, cov ntawv cim zaub mov, huab cua paug thiab kev hloov pauv huab cua.
