Isotopes ntawm ib lub ntsiab lus txhua tus muaj tib yam tshuaj lom neeg tus cwj pwm, tab sis tsis ruaj khov isotopes raug kev puas tsuaj tshwm sim thaumuas lawv tawm hluav taws xob thiab ua tiav lub xeev ruaj khov. Cov cuab yeej ntawm radioisotopes no muaj txiaj ntsig zoo hauv kev khaws zaub mov, kev sib tham archaeological ntawm artifacts thiab kev kuaj mob thiab kev kho mob.
Dab tsi yog qhov tshwj xeeb ntawm isotopes?
Ib qho isotope yog ib qho ntawm ob lossis ntau hom ntawm tib yam tshuaj lom neegCov isotopes sib txawv ntawm ib lub caij muaj tib tus naj npawb ntawm cov protons hauv lub nucleus, muab tib tus lej atomic., tab sis tus lej sib txawv ntawm cov neutrons muab txhua lub ntsiab lus isotope sib txawv atomic hnyav.
Yuav ua li cas yog isotopes?
Lawv feem ntau muaj txiaj ntsig zoo thaum ua qhov kev sim hauv ib puag ncig thiab hauv thaj chaw geochemistry. Cov isotopes tuaj yeem pab txiav txim siab cov tshuaj muaj pes tsawg leeg thiab hnub nyoog ntawm cov zaub mov thiab lwm yam khoom siv geologicalQee cov piv txwv ntawm cov isotopes ruaj khov yog cov isotopes ntawm carbon, potassium, calcium thiab vanadium.
5 siv isotopes yog dab tsi?
Radioactive isotopes pom siv nyob rau hauv kev ua liaj ua teb, kev lag luam zaub mov, tshuaj tua kab, archaeology thiab tshuajRadiocarbon dating, uas ntsuas lub hnub nyoog ntawm cov khoom uas muaj cov pa roj carbon monoxide, siv cov xov tooj cua isotope hu ua carbon-14. Hauv cov tshuaj, gamma rays tawm los ntawm cov khoom siv hluav taws xob yog siv los kuaj cov qog hauv tib neeg lub cev.
2 hom isotopes yog dab tsi?
Isotope Facts
Txhua lub ntsiab muaj isotopes. Muaj ob hom isotopes tseem ceeb: ruaj khov thiab tsis ruaj khov (xov tooj cua). Muaj 254 paub cov isotopes ruaj khov.
