Electrons nrog lub zog siab tshaj theem muaj nyob rau sab nraud lub plhaub ntawm ib qho atom thiab kuj xoob khi rau lub atom . Qhov no sab nraud plhaub yog lub npe hu ua valance plhaub thiab electrons hauv qhov no plhaub hu ua valance electrons. Ua tiav sab nraud plhaub muaj valance ntawm zero.
Ntxiv mus, lub plhaub twg muaj lub zog tshaj plaws?
Cov electron plhaub muaj npe K, L, M, N, O, P, thiab Q; los yog 1, 2, 3, 4, 5, 6, thiab 7; mus los ntawm innermost plhaub sab nraud. Electrons nyob rau hauv lub plhaub sab nrauv muaj lub zog nruab nrab siab dua thiab taug kev deb ntawm lub nucleus tshaj cov nyob rau hauv lub plhaub.
Kuj Paub, lub plhaub lub zog twg muaj zog dua L lossis N? Teb: L yog at a zog dua qib. Far cov plhaub los ntawm nucleus, ntau yog nws zog . K sawv cev plhaub 1, uas nyob ib sab ntawm nucleus ua raws li L , M, N raws.
Khaws qhov no hauv kev txiav txim siab, lub plhaub twg muaj lub zog tsawg kawg nkaus?
Zog theem ntawm atomic electrons The qis zog qib (k plhaub ) tsuas tuaj yeem nyob ntawm ob lub tshuab hluav taws xob, L plhaub los ntawm 8 thiab M plhaub los ntawm 18. K plhaub electrons yog ze tshaj plaws rau lub nucleus.
Cov electrons twg muaj zog tshaj plaws hauv ib lub atom?
Hluav taws xob ntawm siab dua zog theem, uas nyob deb ntawm lub nucleus, muaj ntau zog . Lawv kuj muaj ntau orbitals thiab ntau dua tau tus lej ntawm electrons . Hluav taws xob ntawm sab nraud zog level ib atom hu ua valence electrons.

Lub zog twg yog qhov muaj feem cuam tshuam tshaj plaws hauv kev txiav txim siab tertiary qauv ntawm cov protein?
Lub tertiary qauv ntawm ib tug protein yog peb seem ntawm cov protein. Disulfide bonds, hydrogen bonds, ionic bonds, thiab hydrophobic kev sib cuam tshuam tag nrho cov cuam tshuam rau cov qauv ntawm cov protein
Lub cheeb tsam dej hiav txwv twg muaj biodiversity loj tshaj plaws thiab lub neej dej hiav txwv tshaj plaws?
Epipelagic cheeb tsam nthuav tawm ntawm qhov chaw mus txog 200m nqes. Nws tau txais ntau lub hnub ci thiab yog li muaj cov biodiversity tshaj plaws nyob rau hauv dej hiav txwv. Nws tseem hu ua thaj tsam twilight vim tias lub teeb txwv tsis pub muaj peev xwm lim tau los ntawm cov dej no
Dab tsi yog qhov muaj zog tshaj plaws ntawm lub zog sib xyaw ua ke hauv nitrogen?
Kev piav qhia: Qhov muaj zog tshaj plaws ntawm cov npe shydrogen bonding. Hom kev quab yuam intermolecular no yog kev cuam tshuam uas tshwm sim ntawm hydrogen atoms thiab ib leeg khub onatoms ntawm oxygen, nitrogen thiab / lossis fluorine. Hydrogen bonds yog qhov muaj zog tshaj plaws thaum lub zog dispersion yog qhov qis tshaj
Lub xeev twg ntawm cov teeb meem twg muaj zog tshaj intermolecular rog ntawm attraction?
Raws li qhov kub thiab txias tseem poob qis, qhov teeb meem tsim muaj zog. Vim tias cov khoom tsis muaj zog kinetic, cov khoom tsis muaj 'lub sij hawm' txav mus los, cov khoom muaj 'lub sij hawm' kom nyiam. Yog li ntawd, cov khib nyiab muaj qhov muaj zog tshaj plaws intramolecular rog (vim lawv muaj qhov muaj zog tshaj plaws)
