Hauv ib qho muab keeb , tus naj npawb ntawm neutrons tuaj yeem sib txawv ntawm ib leeg, thaum tus naj npawb ntawm protons tsis yog. Cov txawv versions ntawm tib yam keeb hu ua isotopes. Isotopes yog atoms nrog tib tus naj npawb ntawm protons tab sis muaj ntau tus lej ntawm neutrons.

Ntawm no, cov isotopes sib txawv muaj cov khoom sib txawv?

Tag nrho cov atoms ntawm tib lub ntsiab muaj tib tus naj npawb ntawm protons, tab sis qee qhov yuav muaj qhov sib txawv naj npawb ntawm neutrons. Sib txawv isotopes ntawm ib feem feem ntau muaj tib lub cev thiab tshuaj khoom . Qhov ntawd yog vim lawv muaj tib tus lej ntawm protons thiab electrons.

Ib yam li ntawd, vim li cas cov isotopes sib txawv muaj cov tshuaj lom neeg zoo ib yam? Cov ntsiab lus. Atoms ntawm ib yam lub ntsiab lus uas txawv ntawm lawv cov lej ntawm neutrons hu ua isotopes . Sib txawv isotopes ntawm ib feem feem ntau muaj tib lub cev thiab tshuaj muaj zog vim lawv muaj ib yam tus naj npawb ntawm protons thiab electrons. Feem ntau hydrogen atoms tsis muaj neutron thiab tsuas yog hu ua hydrogen.

Ntxiv rau qhov no, cov isotopes ntawm ib lub caij zoo li cas thiab lawv txawv li cas?

Sib txawv isotopes ntawm tib lub ntsiab muaj tib yam tus lej atomic. Lawv muaj tib yam tus naj npawb ntawm protons. Tus naj npawb atomic yog txiav txim los ntawm tus naj npawb ntawm protons. Isotopes muaj txawv coob tus lej, ho, vim lawv muaj txawv naj npawb ntawm neutrons.

Yuav ua li cas koj txiav txim siab qhov feem ntau isotope?

Tshem tawm tus lej atomic (tus naj npawb ntawm cov protons) los ntawm qhov hnyav atomic sib npaug. Qhov no ua rau koj muaj pes tsawg tus neutrons nyob rau hauv feem ntau isotope . Siv lub rooj sib tham sib tham ntawm lub sijhawm Berkeley Laboratory Isotopes Qhov project rau nrhiav lwm yam isotopes ntawm cov khoom ntawd muaj nyob.
