C decays los ntawm tus txheej txheem hu ua beta decay. Thaum lub sijhawm txheej txheem no, ib qho atom ntawm 14 C decays rau hauv an atom ntawm 14N, thaum twg ntawm cov neutrons nyob rau hauv cov pa roj carbon atom ua ib tug proton. Qhov no nce tus naj npawb ntawm cov protons hauv atom los ntawm ib qho, tsim cov nitrogen atom es tsis yog carbon atom.
C 14 Yuav ua li cas yog tias nws dhau los ntawm beta lwj?
Carbon-14 lwj mus rau nitrogen-14 dhau ntawm beta lwj.
Dab tsi yog cov khoom lag luam thaum lub atom ntawm C 14 nkag mus rau beta lwj?
Carbon-14 dhau mus beta lwj, hloov mus rau a nitrogen-14 nucleus. Nco ntsoov tias beta decay nce tus naj npawb atomic los ntawm ib qho, tab sis tus lej loj tseem zoo li qub.
Dab tsi yog qhov sib npaug ntawm cov pa roj carbon-14?
Carbon 14 yog ib hom carbon uas decays dhau sij hawm. Tus nqi ntawm cov pa roj carbon 14 muaj nyob hauv cov nroj tsuag khaws cia yog ua qauv los ntawm kev sib npaug f(t)=10e^{-ct}.
c14 lwj mus rau dab tsi?
Carbon-14 yog qhov tsis tshua muaj cov pa roj carbon nrog yim neutrons. Nws yog radioactive thiab decays thaum lub sij hawm. Thaum carbon-14 decays, ib tug neutron hloov mus ua ib tug proton thiab nws poob ib electron los ua nitrogen-14.
