Cov qhov sib txawv ntawm cov ntsiab lus isotope thiab nuclide tuaj yeem tsis meej pem, thiab lawv feem ntau siv sib hloov. Lub sij hawm nuclide yog ntau generic thiab yog siv thaum xa mus rau nuclei ntawm txawv cov ntsiab lus. Isotope yog qhov zoo tshaj plaws siv thaum xa mus rau ntau yam sib txawv nuclides ntawm tib lub ntsiab.

Tsis tas li ntawd, puas yog nuclide thiab isotope tib yam?

Ib txheej ntawm nuclides nrog sib npaug proton tooj (atomic naj npawb), piv txwv li, ntawm cov ib yam chemical element tab sis txawv neutron tooj, hu ua isotopes ntawm lub ntsiab. Tshwj xeeb nuclides tseem feem ntau xoob hu ua " isotopes ", tab sis lub sij hawm " nuclide " yog qhov tseeb (piv txwv li, thaum Z tsis kho).

Tom qab ntawd, lo lus nug yog, qhov txawv ntawm nuclide thiab nucleus yog dab tsi? A nucleus yog ib feem ntawm ib qho atom uas koj tab tom ua raws li tus txheej txheem. A nuclide yog ib chav kawm ntawm nuclei nrog tib tus naj npawb ntawm protons thiab neutrons. Yog li ntawd 5 nuclei ntawm deuterium tag nrho yog tib yam nuclide ,mas 5 txawv nuclei.

Hais txog qhov no, lub cim nuclide yog dab tsi?

Nuclide . Nuclides yog ib hom atoms lossis nuclei. Txhua nuclide muaj cov tshuaj lom neeg cim (E) nrog rau tus lej atomic (Z), tus naj npawb ntawm protons hauv lub nucleus, thiab tus lej loj (A), tag nrho cov protons thiab neutrons hauv lub nucleus. Cov cim rau lub caij yog raws li qhia hauv qab no: AZE.

Dab tsi yog nuclear isotope?

Paub Nuclear Txhua lub atom ntawm ib lub caij ib txwm muaj tib tus lej ntawm protons. Radioactive isotopes los yog radioisotopes, yog isotopes ntawm ib lub caij uas muaj cov nucleus tsis ruaj khov uas lwj (emitting alpha, beta, lossis gamma rays) kom txog thaum muaj kev ruaj ntseg. Cov khoom ruaj khov kawg yog nonradioactive isotope ntawm lwm yam.
