Isotopes ntawm ib lub ntsiab qhia tib tus naj npawb ntawm protons tab sis muaj ntau tus lej ntawm neutrons. Cia peb siv carbon ua piv txwv. Muaj peb 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.

Hais txog qhov no, vim li cas carbon 12 yog isotope?

1 Teb. Vim tias elemental carbon muaj ob peb isotopes . Tag nrho carbon nuclei muaj 6 protons, tab sis qee qhov carbon nuclei muaj ntau dua 6 neutrons.

Tom qab, lo lus nug yog, carbon isotopes tsim li cas? Ntuj isotopes C yog tsim los ntawm thermal neutrons los ntawm cosmic hluav taws xob nyob rau hauv cov huab cua sab saud, thiab yog thauj mus rau lub ntiaj teb kom absorbed los ntawm cov khoom muaj sia nyob.

Hauv qhov no, vim li cas carbon 14 tsis suav tias yog isotope?

Vim tias atoms ib txwm muaj tib tus nqi ntawm protons thiab neutrons. Lawv txhua tus muaj tib tus lej atomic, tib tus lej ntawm protons. Piav vim li cas carbon - 14 thiab nitrogen- 14 yog tsis suav tias yog isotopes ntawm ib leeg? Vim lawv yog ob yam sib txawv.

Dab tsi ua rau ib qho isotope?

Cov atoms ntawm cov khoom siv tshuaj muaj peev xwm muaj nyob hauv ntau hom. Cov no hu ua isotopes . Lawv muaj tib tus naj npawb ntawm protons (thiab electrons), tab sis sib txawv ntawm cov neutrons. txawv isotopes ntawm tib lub ntsiab muaj ntau pawg. Mass yog lo lus rau ntau npaum li cas cov khoom (los yog teeb meem) ib yam dab tsi muaj.
