Cov pa roj carbon , piv txwv li, muaj peb qhov tshwm sim isotopes : 12C ( carbon - 12 ), 13 C ( carbon -13) thiab 14 C ( carbon -14). C yog xov tooj cua thiab muab tawm beta rays uas tau siv los ntsuas cov plua plav ua pa, tab sis nws cov concentration hauv cov thee tsawg, ntawm qhov kev txiav txim ntawm 1 × 10−10 feem pua ntawm atmospheric carbon dioxide.
Ib yam li ntawd, tib neeg nug, yog carbon 12 yog isotope?
Ib ISOTOPE txhais tau hais tias versions ntawm ib lub caij nrog ntau tus lej ntawm neutrons. Tag nrho carbon atoms muaj 6 protons; uas yog qhov ua rau nws carbon . Cov pa roj carbon -11 muaj 6 protons thiab 5 neutrons. Cov pa roj carbon - 12 muaj 6 protons thiab 6 neutrons.
Lub cim carbon 12 txhais li cas? Wiktionary. carbon - 12 (Noun) Qhov ntau tshaj ntawm ob lub isotopes ruaj khov ntawm carbon , muaj rau protons thiab rau neutrons; nws yog tus qauv rau atomic hnyav thiab yog siv rau txhais cov mole.
Tsis tas li ntawd, qhov twg isotope ntawm carbon yog radioactive?
14C
Vim li cas carbon 12 yog ib qho tseem ceeb ntawm isotope?
Cov pa roj carbon 12 tau xaiv vim tias cov tshuaj atomic hnyav raws li C12 yuav luag zoo tib yam rau cov tshuaj atomic hnyav raws li kev sib xyaw ntawm cov pa oxygen.
