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.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov txawv ntawm instantaneous thiab nruab nrab ceev dab tsi yog qhov piv txwv loj tshaj ntawm kev ceev ceev?
Qhov nruab nrab ceev yog qhov ceev nruab nrab ntawm lub sijhawm. Instantaneous ceev yuav yog qhov ceev txhua qhov muab tam sim ntawd hauv lub sijhawm ntawd, ntsuas nrog lub ntsuas ntsuas lub sijhawm
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
