Qhov seem peb electrons yuav mus rau hauv 2p orbital. Yog li N electron configuration yuav yog 1s22s ib22 ib p3. Lub configuration sau ntawv rau Nitrogen (N) muab txoj hauv kev yooj yim rau cov kws tshawb fawb los sau thiab sib txuas lus li cas electrons tau teem ib ncig ntawm lub nucleus ntawm Nitrogen atom.
Ntawm no, dab tsi yog qhov valence electron configuration rau nitrogen atom?
[Nws] 2s2 2p3
Ib tug kuj yuav nug, vim li cas Valency ntawm nitrogen yog 5? Nitrogen pom tias muaj 3 los yog 5 valus electrons thiab nyob rau sab saum toj ntawm Pawg 15 ntawm lub rooj sib tham. Nws tuaj yeem muaj 3 lossis 5 valus electrons vim nws muaj peev xwm sib txuas rau sab nrauv 2p thiab 2s orbitals. Nitrogen ua DNA nyob rau hauv daim ntawv ntawm nitrogenous bases thiab nyob rau hauv neurotransmitters.
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov tseem ceeb valence electron configuration rau potassium?
Yog li, poov tshuaj muaj ib electron configuration ntawm [Ar]4s1. Vim li no, poov tshuaj sib raug rau Li thiab Na hauv nws valence plhaub configuration . Tom ntej no hluav taws xob yog ntxiv kom tiav 4s subshell thiab calcium muaj ib qho electron configuration ntawm [Ar]4s2.
Koj txiav txim siab Valency li cas?
Cov valency ntawm ib lub atom yog sib npaug rau cov xov tooj ntawm electrons nyob rau hauv lub plhaub sab nraud yog tias tus lej ntawd yog plaub lossis tsawg dua. Txwv tsis pub, cov valency yog sib npaug rau yim rho tawm tus naj npawb ntawm electrons nyob rau hauv lub plhaub sab nrauv. Thaum koj paub tus naj npawb ntawm electrons, koj tuaj yeem yooj yim xam tus valency.

Dab tsi yog qhov ua tiav hauv lub xeev electron configuration rau lub gallium atom?
Hauv av xeev electron configuration ntawm hauv av xeev gaseous nruab nrab gallium yog [Ar]. 3d10 ua. 4s2 ua. 4p1 thiab lub sij hawm cim yog 2P1/2
Vim li cas qhov tseem ceeb ntawm qhov tseem ceeb?
Thaum koj pom tus nqi kiag li hauv qhov teeb meem lossis qhov sib npaug, nws txhais tau hais tias txhua yam nyob hauv tus nqi tiag tiag yog qhov zoo. Cov txiaj ntsig tsis zoo feem ntau siv rau hauv cov teeb meem cuam tshuam nrog kev nyob deb thiab qee zaum siv nrog qhov tsis sib xws. Qhov ntawd yog qhov tseem ceeb uas yuav tsum nco ntsoov nws zoo li qhov deb ntawm xoom
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 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
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
