Isotopes yog atoms ntawm
tib lub caij uas muaj cov lej sib txawv ntawm cov neutrons tab sis tib tus naj npawb ntawm protons thiab electrons . Qhov sib txawv ntawm cov neutrons ntawm ntau cov isotopes ntawm ib lub caij txhais tau hais tias ntau cov isotopes muaj ntau qhov sib txawv.
Ib qho piv txwv ntawm isotopes ntawm tib lub ntsiab yog dab tsi?
Isotopes ntawm ib lub ntsiab lus qhia tib tus lej ntawm protons tab sis muaj cov lej sib txawv ntawm neutrons. Cia peb siv carbon ua piv txwv. Muaj peb lub isotopes ntawm carbon pom nyob rau hauv cov xwm - 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.
Koj pom isotopes ntawm tib lub caij li cas?
rho tawm tus lej atomic (tus naj npawb ntawm cov protons) los ntawm qhov hnyav atomic sib npaug Qhov no muab koj cov naj npawb ntawm cov neutrons hauv cov isotope feem ntau. Siv lub rooj sib tham sib tham nyob rau ntawm Berkeley Laboratory Isotopes Project txhawm rau nrhiav seb lwm cov isotopes ntawm lub caij muaj nyob.
Yuav ua li cas 3 yam ua isotopes ntawm tib lub ntsiab muaj sib xws?
(iii) Thiab yog tias nws yog tib lub isotope, txhua lub nucleus muaj tib yam number of neutrons, qhov twg neutron yog ib qho loj heev, qhov tseem ceeb ntawm xoom nqi. Tus naj npawb ntawm cov protons thiab neutrons muab tus kheej ntawm isotope. Muaj peb hom isotopes ntawm hydrogen: protium, 1H; deuterium, 2H, andtritium, 3H.
Yuav ua li cas sib txawv isotopes ntawm tib lub ntsiab muaj sib xws?
Isotopes. Ib qho isotope yog ib qho ntawm ob lossis ntau hom ntawm tib yam tshuaj lom neeg. Cov isotopes sib txawv ntawm ib lub caij muaj tib tus naj npawb ntawm protons hauv lub nucleus, muab lawv tib tus lej atomic, tab sis tus lej sib txawv ntawm cov neutrons muab txhua lub ntsiab lus isotope sib txawv atomic hnyav.
