Cov kev hloov hlau tau muab lawv lub npe vim tias lawv muaj qhov chaw nruab nrab ntawm Pawg 2A (tam sim no Pawg 2) thiab Pawg 3A (tam sim no Pawg 13) hauv pawg loj cov ntsiab lus . Yog li ntawd, thiaj li yuav tau txais los ntawm calcium mus rau gallium nyob rau hauv Lub Sijhawm Table, koj yuav tsum tau kev hloov pauv koj txoj kev los ntawm thawj kab ntawm d thaiv (Sc → Zn).
Tib neeg kuj nug, vim li cas cov ntsiab lus hloov pauv hu ua qhov ntawd?
The d-block cov ntsiab lus uas yog cov ntsiab lus los ntawm pawg 3-12 yog hu ua kev hloov pauv . Qhov no yog vim hais tias lawv lub cev thiab tshuaj muaj zog yog nruab nrab ntawm s-block thiab p-block zog. Yog li cov no cov ntsiab lus ua tus choj ntawm s-block rau p-block thiab li no lawv yog lub npe hu ua Hloov cov ntsiab lus.
Qhov thib ob, qhov kev hloov pauv thaum ntxov yog dab tsi? Pawg 3 txog 7 (IUPAC -- IIIB-VIIB lossis IIIA-VIIA ua ntej) hu ua thaum ntxov hloov hlau vim lawv tsim thawj ib nrab ntawm cov kev hloov pauv series. Qhov no sib piv nrog cov lig kev hloov hlau (IUPAC pawg 8 txog 12) uas zoo li muaj qhov siab tshaj plaws ntawm 2 lossis 3, thiab cov kev ua haujlwm nrawm nrawm.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog hu ua kev hloov pauv cov ntsiab lus?
Teb: Feem ntau ntawm cov cov ntsiab lus nyob rau lub sij hawm Table yog kev hloov hlau . Cov no yog cov ntsiab lus uas muaj ib nrab sau d sublevel orbitals. Hnub no cov no cov ntsiab lus tseem hu ua d block cov ntsiab lus . Cov Hloov cov ntsiab lus txhua tus yog hlau , yog li ntawd lawv kuj hu ua kev hloov hlau.
Cov pab pawg twg hu ua kev hloov pauv hlau?
Ntau tus kws tshawb fawb piav qhia txog " kev hloov hlau " as any keeb nyob rau hauv lub d-block ntawm lub periodic rooj, uas muaj xws li pab pawg 3 mus rau 12 ntawm lub rooj sib tham. Hauv kev xyaum tiag tiag, f-block lanthanide thiab actinide series kuj raug txiav txim siab kev hloov hlau thiab yog hu ua "hauv kev hloov hlau ".

Vim li cas cov hnub qub dhau los ntawm kev hloov pauv hloov pauv?
Stellar evolution yog tus txheej txheem uas lub hnub qub hloov pauv nyob rau lub sijhawm. Cov hnub qub uas muaj tsawg kawg yog ib nrab ntawm lub hnub tuaj yeem pib tsim lub zog los ntawm kev sib xyaw ntawm helium ntawm lawv cov tub ntxhais, thaum lub hnub qub ntau dua tuaj yeem sib xyaw cov ntsiab lus hnyav dua raws li cov khoom sib xyaw ua ke
Dab tsi yog qhov kev hloov pauv hloov pauv?
Kev hloov pauv, hauv molecular biology, yog hais txog kev hloov pauv hauv deoxyribonucleic acid (DNA), qhov twg ib qho (ob lub nplhaib) purine hloov pauv rau (ib lub nplhaib) pyrimidine, los yog vice versa
Vim li cas tom qab kev hloov pauv kev hloov pauv tseem ceeb?
Kev hloov pauv tom qab kev txhais lus (PTMs) xws li glycosylation thiab phosphorylation ua lub luag haujlwm tseem ceeb ntawm kev ua haujlwm ntawm hemostatic proteins thiab tseem ceeb heev hauv kev teeb tsa kab mob. Xws li theem nrab hloov pauv rau cov proteins hemostatic muaj ntau yam cuam tshuam rau lawv lub peev xwm los cuam tshuam nrog lwm cov proteins
Dab tsi tsim cov roj siab thiab nws hloov pauv li cas nrog kev hloov pauv hauv kinetic zog?
Gas siab yog tshwm sim los ntawm kev sib tsoo ntawm cov khoom siv roj nrog rau sab hauv ntawm lub thawv thaum lawv sib tsoo nrog thiab tawm dag zog rau ntawm phab ntsa ntim. Tom qab ntawd cov roj yog cua sov. Raws li qhov kub ntawm cov roj nce, cov khoom tau nce lub zog kinetic thiab lawv cov nrawm nrawm
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
