Cov kauj ruam
- Nrhiav koj tus lej atomic.
- Txiav txim siab tus nqi ntawm lub atom.
- Nco cov npe ntawm cov orbitals.
- Nkag siab txog kev teeb tsa hluav taws xob.
- Nco qhov kev txiav txim ntawm lub orbitals.
- Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom.
- Siv lub sij hawm ntev raws li qhov pom kev luv luv.
Ib yam li ntawd, cov kauj ruam los sau electron configuration yog dab tsi?

Qhov thib ob, Subshell yog dab tsi? A subshell yog ib tug subdivision ntawm electron plhaub sib cais los ntawm electron orbitals. Subshells yog sau npe s, p, d, thiab f hauv kev teeb tsa hluav taws xob.
Ib yam li ntawd, nws raug nug, Hund txoj cai yog dab tsi?
Hund txoj cai . Hund txoj cai : Txhua lub orbital nyob rau hauv lub subshell yog singly nyob nrog ib tug electron ua ntej ib qho orbital yog ob zaug nyob, thiab tag nrho cov electrons nyob rau hauv singly occupied orbitals muaj tib lub kiv.
Muaj pes tsawg electrons nyob hauv txhua lub plhaub?
Txhua lub plhaub muaj peev xwm tsuas muaj tus naj npawb ruaj khov ntawm cov hluav taws xob: Thawj lub plhaub tuaj yeem tuav tau ob tug electrons , lub plhaub thib ob tuaj yeem tuav tau txog yim (2 + 6) electrons, lub plhaub thib peb tuaj yeem tuav tau 18 (2 + 6 + 10) thiab lwm yam. Cov qauv dav dav yog tias lub plhaub nth tuaj yeem tuav txog 2 (n2) electrons.

Yog vim li cas transcription yog ib kauj ruam tsim nyog nyob rau hauv protein synthesis?
Lub Art ntawm Protein Synthesis Nyob rau hauv eukaryotic hlwb, transcription tshwm sim nyob rau hauv lub nucleus. Thaum lub sijhawm sau ntawv, DNA yog siv los ua tus qauv los ua ib qho molecule of messenger RNA (mRNA). Thaum lub sij hawm kev txhais lus, cov noob caj noob ces hauv mRNA yog nyeem thiab siv los ua cov protein
Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
