Txhua square ntawm lub rooj zaum muab yam tsawg kawg nkaus lub npe keeb , nws cov cim, atomic naj npawb thiab txheeb ze atomic mass (atomic hnyav).
Nyob rau hauv no, dab tsi yog pom nyob rau hauv qab ntawm lub ntsiab square ntawm lub periodic rooj?
Hauv txhua qhov element square , cov ntaub ntawv ntawm lub ntsiab cim, atomic naj npawb, atomic mass, electronegativity, electron configuration, thiab valence tooj yuav ua tau pom . Nyob ntawm hauv qab ntawm daim ntawv qhia hnub yog ob kab thaiv ntawm cov ntsiab lus uas muaj cov lanthanoids thiab actinides.
Cov qauv dab tsi muaj nyob rau hauv lub rooj zaum? Lub caij nyoog sib txawv yog tshwj xeeb qauv nyob rau hauv cov khoom ntawm chemical ntsiab lus uas yog qhia nyob rau hauv lub daim ntawv qhia hnub ntawm cov ntsiab lus. Major ntu ntu muaj xws li electronegativity, ionization zog, electron affinity, atomic radii, ionic radius, metallic cim, thiab tshuaj reactivity.
Hais txog qhov no, txhua lub thawv ntawm lub rooj zaum muaj dab tsi?
Cov lub thawv uas muaj txhua yam khoom cov ntaub ntawv yog lub npe hu ua keeb tus yuam sij. Txhua tus yuam sij muaj ib lub ntsiab lub npe, cim cim, atomic hnyav thiab atomic naj npawb.
Koj tuaj yeem pom dab tsi ntawm lub rooj zaum?
Cov daim ntawv qhia hnub , kuj hu ua daim ntawv qhia hnub ntawm cov ntsiab lus, yog ib tug tabular zaub ntawm cov ntsiab lus tshuaj, uas yog teem los ntawm atomic tooj, electron configuration, thiab rov tshwm sim chemical zog.

Ob qhov tseem ceeb ntawm lub voj voog ntawm tes yog dab tsi thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Muaj ob theem tseem ceeb hauv lub voj voog ntawm tes. Thawj theem yog interphase thaum lub cell loj hlob thiab replicates nws DNA. Qhov thib ob yog theem mitotic (M-Phase) thaum lub sijhawm cell faib thiab hloov ib daim qauv ntawm nws cov DNA mus rau ob lub hlwb zoo tib yam
Dab tsi pov thawj koj tuaj yeem hais txog qhov xwm txheej ntawm lub teeb?

Dab tsi yog 2 qhov tseem ceeb ntawm lub voj voog ntawm tes thiab dab tsi tshwm sim rau lub cell hauv txhua theem?
Cov xwm txheej no tuaj yeem muab faib ua ob qhov tseem ceeb: interphase (hauv nruab nrab ntawm kev sib faib theem ua pawg G1 theem, S theem, G2 theem), thaum lub xov tooj ntawm tes tsim thiab ua nrog nws cov haujlwm metabolic; mitotic theem (M mitosis), thaum lub sij hawm lub cell yog replicating nws tus kheej
Yuav ua li cas oxygen tshwm sim hauv xwm piav qhia txog lub voj voog oxygen hauv qhov xwm txheej?
Piav lub voj voog oxygen hauv qhov xwm txheej. Oxygen muaj nyob rau hauv ob hom sib txawv hauv qhov xwm txheej. Cov ntaub ntawv no tshwm sim raws li cov pa roj carbon monoxide 21% thiab ua ke hauv daim ntawv oxides ntawm hlau thiab nonmetals, nyob rau hauv lub ntiaj teb crust, cua thiab dej. Oxygen rov qab mus rau qhov chaw los ntawm cov txheej txheem hu ua photosynthesis
Txhua tus neeg hauv ntiaj teb puas tuaj yeem pom lub hli tib lub sijhawm?
Kwv yees li ib feem peb ntawm lub ntiaj teb tuaj yeem pom lub hli txhua lub sijhawm, lossis ib nrab yog tias lub hli pom ntawm qab ntug mus rau qab ntug. Txhua leej txhua tus pom lub hli ntawm ntau txoj haujlwm tib lub sijhawm los ntawm ib nrab ntawm lub ntiaj teb tib lub sijhawm
