Ib tug electron khub electron khub Lone khub muaj nyob rau hauv sab nraud ntawm lub plhaub ntawm lub atoms. … Electron khub yog li ntawd suav hais tias yog ib leeg khub yog tias ob lub electrons raug ua ke tab sis tsis siv rau hauv kev sib txuas tshuaj. Yog li, tus naj npawb ntawm ib khub electrons ntxiv rau cov xov tooj ntawm cov khoom siv hluav taws xob sib npaug ntawm tag nrho cov valence electrons nyob ib ncig ntawm ib lub atom. https://en.wikipedia.org › wiki › Lone_pair
Ib khub - Wikipedia
nyob rau hauv ib qho s-orbital muaj qhov sib npaug ntawm cov hluav taws xob sib luag, thiab yog li tsis tuaj yeem cuam tshuam cov duab ntawm cov molecule. Txawm li cas los xij, nws tsis yog raws nraim lub orbital uas yog stereochemically (hauv) nquag, nws yog cov electrons, thiab yog li cov lus pom ntau dua yog "stereochemically (hauv) ib leeg khub ".
Dab tsi yog stereochemically active ib khub?
Nyob hauv chemistry, stereochemically active ib leeg khub feem ntau tau piav raws li ib qho tseem ceeb uas tsis yog kev sib raug zoo, thiab cov paj laum tsis ntev los no tau tsom mus rau kev nkag siab cov txiaj ntsig ntawm tus khub ib leeg qhia ntawm lub cev. xws li thermal conductivity.
Stereochemically inert yog dab tsi?
stereochemically inactive s orbital txhais tau hais tias lub xub ntiag ntawm s orbital ib leeg khub muaj liitle los yog tsis muaj kev cuam tshuam rau cov geometry thiab cov duab ntawm cov siv lead ua. ntawm s orbital tsis tuaj li piv rau p orbital.
Vim li cas oxygen thiaj muaj 2 leeg xwb?
Nws muaj rau valence plhaub electrons thiab li no, muaj peb valence electron khub nyob rau hauv ib tug oxygen atom. Peb paub tias oxygen tsim ob daim ntawv cog lus thiab yog li ob lub tshuab hluav taws xob tau koom nrog ua ob daim ntawv cog lus. Yog li, ob lub hluav taws xob sab laug uas tsis koom nrog kev sib raug zoo Li no, oxygen muaj ob leeg xwb.
Stereoactive ib leeg yog dab tsi?
Txawm li cas los xij, tin (II) fluorides paub tias yuav tsum tau covalent ib txwm nrog ib tug hybridized ib khub ntawm tin, uas tau txo qis kev sib koom tes thiab yog li ntawd ib tug heev distorted polyhedron ntawm kev sib koom tes. Xws li ib tug hybridized ib leeg yog hais tias yog "stereoactive ".
