Ntau cov ntsiab lus hnyav dua hlau tsim supernova explosions. Tus nqi ntawm lub zog tso tawm thaum lub sij hawm supernova tawg yog siab heev uas lub zog pub dawb thiab cov neutrons dawb streaming los ntawm cov tub ntxhais sib tsoo ua rau muaj kev cuam tshuam loj heev, ntev dhau los ntawm kev tsim ntawm hlau.
Xav txog qhov no, cov hnub qub tuaj yeem tsim cov ntsiab lus hnyav dua li cov hlau?
Tom qab cov hydrogen nyob rau hauv lub hnub qub lub core yog tas lawm, lub hnub qub ua tau fuse helium rau tsim zuj zus hnyav zog , carbon thiab oxygen thiab lwm yam, mus txog rau hlau thiab nickel raug tsim. Up rau qhov no, cov txheej txheem fusion tso tawm lub zog. Kev tsim ntawm cov ntsiab lus hnyav dua hlau thiab npib tsib xee yuav tsum muaj lub zog nkag.
Kuj Paub, cov ntsiab lus hnyav dua tuaj qhov twg? Tag nrho cov cov ntsiab lus hnyav dua tshaj txhuas yog tsim los ntawm tawg r-txheej txheem nucleosynthesis nyob rau hauv supernova explosions, colliding neutron hnub qub thiab lwm yam. hnyav dua tshaj hlau (peak) cov ntsiab lus yog 50:50.
Ib yam li ntawd, nws tau nug, qhov twg feem ntau ntawm cov ntsiab lus hnyav dua li hlau daim ntawv quizlet?
Cov ntsiab lus hnyav dua hlau tuaj yeem yog tsim nyob rau hauv cov hnub qub loj heev los ntawm absorbing neutrons, nyob rau hauv ib tug txheej txheem hu ua neutron capture. Qhov no yooj yim dua tshaj fusion vim hais tias neutrons yog nruab nrab thiab tsis repelled los ntawm ib tug atomic nucleus.
Puas yog tag nrho cov ntsiab lus hnyav dua li hydrogen tuaj ntawm qhov twg?
Teb thiab piav qhia: Cov ntsiab lus hnyav dua li hydrogen thiab helium los ntawm cov tshuaj tiv thaiv hauv cov hnub qub. Thaum hydrogen thiab helium yog paub rau los ntawm lub suab loj, kab

Yuav ua li cas cov ntsiab lus hnyav dua hlau yog tsim?
Ntau lub ntsiab lus hnyav dua hlau yog tsim supernova tawg. Tus nqi ntawm lub zog tso tawm thaum lub sij hawm supernova tawg yog siab heev uas lub zog pub dawb thiab cov neutrons dawb streaming los ntawm cov tub ntxhais sib tsoo ua rau muaj kev cuam tshuam loj heev, ntev dhau los ntawm kev tsim cov hlau
Cov pab pawg twg ntawm cov ntsiab lus tsuas muaj tsis yog hlau?
Kev piav qhia: Pawg VIIA yog tib pawg hauv lub sijhawm uas txhua lub ntsiab lus yog nonmetals. Cov pab pawg no muaj F, Cl, Br, I thiab At.Lwm lub npe ntawm pab pawg no yog halogen uas txhais tau tias cov khoom siv ntsev
Vim li cas cov ntsiab lus thiab cov ntsiab lus yog cov tshuaj ntshiab?
Elements thiab compounds yog ob qho tib si piv txwv ntawm cov khoom ntshiab. Ib yam khoom uas tuaj yeem tawg mus rau hauv cov tshuaj lom neeg yooj yim dua (vim tias nws muaj ntau dua ib qho) yog ib qho khoom sib xyaw. Piv txwv li, dej yog acompound tsim los ntawm cov ntsiab lus hydrogen thiaboxygen
Qhov txawv ntawm qhov hnyav thiab qhov hnyav yog dab tsi?
Raws li lub npe qhov sib txawv ntawm qhov hnyav thiab hnyav yog tias lub nra yog lub nra; qhov hnyav yuav tsum tau nqa thaum qhov hnyav yog lub zog ntawm ib qho khoom vim qhov kev sib tw ntawm nws thiab lub ntiaj teb (lossis yam khoom siv astronomical nws feem ntau cuam tshuam los ntawm)
Cov ntsiab lus hnyav tuaj qhov twg los?
Tag nrho cov ntsiab lus hnyav dua cov hlau lead yog tsim los ntawm tawg r-txheej txheem nucleosynthesis nyob rau hauv supernova explosions, colliding neutron hnub qub thiab lwm yam. Qhov sib cais ntawm r-txheej txheem thiab s-txheej txheem ntau lawm ntawm hnyav dua hlau (peak) hais txog 50:50
