Ib qho isotope muaj npe tom qab lub caij thiab cov lej ntawm nws cov atoms. … Txhua peb isotopes ntawm hydrogen muaj cov khoom siv tshuaj zoo tib yam. Qhov no yog vim tus naj npawb ntawm cov electrons txiav txim siab cov khoom siv tshuaj, thiab tag nrho peb cov isotopes muaj ib qho hluav taws xob hauv lawv cov atoms.
Puas muaj tshuaj lom neeg txawv hauv isotopes?
Atoms ntawm tib lub ntsiab lus uas txawv ntawm lawv cov lej ntawm neutrons hu ua isotopes. … Cov isotopes sib txawv ntawm ib lub caij feem ntau muaj qhov tib lub cev thiab tshuaj lom neegvim tias lawv muaj tib tus lej ntawm protons thiab electrons.
Vim li cas cov isotopes muaj cov khoom siv tshuaj tib yam?
Qhov no yog vim isotopes ntawm ib lub caij muaj tib tus lej ntawm cov hluav taws xob ua ib qho atom ntawm lub caij. Tab sis lawv muaj cov lej sib txawv ntawm cov neutrons uas cuam tshuam rau cov lej loj. Ntau tus lej txiav txim siab lub cev. Li no cov isotopes muaj cov tshuaj zoo sib xws tab sis cov khoom sib txawv ntawm lub cev.
YPuas isotopes muaj tib yam tshuaj thiab cov khoom siv nuclear?
Isotopes muaj cov khoom siv tshuaj zoo tib yam, tseem muaj cov khoom siv nuclear sib txawv. … Piv txwv li, muaj peb lub isotopes ntawm hydrogen. Ob ntawm cov isotopes ruaj khov, (tsis yog xov tooj cua), tab sis tritium (ib qho proton thiab ob lub neutrons) tsis ruaj khov.
3 piv txwv ntawm isotopes yog dab tsi?
Piv txwv li, carbon-12, carbon-13, thiabcarbon-14 yog peb cov isotopes ntawm cov pa roj carbon nrog cov lej 12, 13, thiab 14, feem. Cov atomic tooj ntawm carbon yog 6, uas txhais tau hais tias txhua txhua carbon atom muaj 6 protons thiaj li hais tias cov neutron tooj ntawm cov isotopes yog 6, 7, thiab 8 feem.
