Cov hluav taws xob sab nraud tau dhau los ua delocalised hla tag nrho cov qauv hlau. Qhov no txhais tau hais tias lawv tsis txuas rau ib qho atom lossis khub ntawm atoms, tab sis tuaj yeem xav txog kev txav mus los ntawm txhua tus qauv. Yog li txhua lub atom sab nrauv electrons tau koom nrog hauv qhov kev txiav txim siab delocalisation Hauv chemistry, delocalized electrons yog electrons nyob rau hauv ib lub molecule, ion lossis khoom hlau uas tsis cuam tshuam nrog ib lub atom lossis covalent daim ntawv cog lus. … Hauv quantum chemistry, qhov no yog hais txog molecular orbital electrons uas tau txuas mus rau ntau lub atoms uas nyob ib sab. https://en.wikipedia.org › wiki › Delocalized_electron

los yog hiav txwv ntawm electrons.
Dab tsi yog delocalized electrons hauv ib lub hlau?
Hauv chemistry, delocalized electrons yog electrons nyob rau hauv ib lub molecule, ion los yog khoom hlauuas tsis txuam nrog ib qho atom lossis ib daim ntawv cog lus. … Hauv quantum chemistry, qhov no yog hais txog molecular orbital electrons uas tau txuas mus rau ntau lub atoms uas nyob ib sab.
Yuav ua li cas cov electrons hauv cov hlau ua delocalized electrons?
Nyob hauv metallic bonds, the valence electrons los ntawm s thiab p orbitals ntawm kev sib cuam tshuam hlau atoms delocalize. Qhov ntawd yog hais tias, es tsis txhob orbiting lawv cov hlau atoms, lawv tsim ib "hiav txwv" ntawm electrons uas nyob ib ncig ntawm lub zoo atomic nuclei ntawm interacting hlau ions.
Yuav ua li cas cov ntsiab lus muaj delocalised electrons?
Metallic bonding tshwm sim ntawm atoms ntawm metal elements - Lithium, Beryllium, Sodium, Magnesium, Aluminium thiab Calcium. Cov electrons sab nraud yog delocalised (dawb txav). Qhov no ua rau lub zog electrostatic ntawm attraction ntawm cov hlau zoo ions thiab qhov tsis zoo delocalised electrons.
Yuav ua li cas koj thiaj paub yog tias electrons raug delocalized?
Txoj kev yooj yim tshaj plaws kom pom cov hluav taws xob delocalized yog los piv cov chaw hluav taws xob hauv ob daim ntawv resonance. Yog hais tias ib khub tshwm nyob rau hauv ib qho chaw hauv ib daim ntawv, thiab nyob rau hauv ib qho chaw sib txawv ntawm lwm daim ntawv, tus khub yog delocalized.

Ntau npaum li cas delocalised electrons hauv lub nplhaib benzene?
Nyob rau hauv lub nplhaib aromatic yooj yim ntawm benzene lub delocalization ntawm rau π electrons π electrons Nyob rau hauv chemistry, pi bonds (π bonds) yog covalent tshuaj bonds qhov twg ob lobes ntawm ib lub orbital ntawm ib lub atom sib tshooj ob lobes.
Dab tsi yog delocalised electrons bbc bitesize?
Cov electrons los ntawm lub plhaub sab nraud ntawm cov hlau atoms yog delocalised, thiab muaj kev ywj pheej los ntawm tag nrho cov qauv. Qhov kev sib koom ntawm cov hluav taws xob delocalised no ua rau muaj zog hlau sib txuas hlau hlau sib txuas Lub zog ntawm daim ntawv cog lusCov atoms hauv cov hlau muajmuaj zog txaus nyiam ntawm lawv Ntau lub zog yuav tsum kov yeej nws.
Vim li cas ib yam khoom hlau tsis muaj hlau nplaum nyiam rau cov hlau nplaum?
Thaum cov hlau nplaum raug coj los ze rau cov khoom siv ferromagnetic yav dhau los uas tsis muaj hlau nplaum, nws ua rau cov hlau nplaum hauv zos ntawm cov khoom uas tsis zoo li cov ncej ze tshaj, ib yam li hauv. unmagnetized khoom rau cov hlau nplaum raws li daim duab hauv .
Yog delocalised electrons tsis zoo?
Tus nqi delocalized yog tus nqi raug cai uas tshwm sim ntawm ib lub atom hauv qee daim ntawv resonance thiab ntawm lwm cov atoms hauv lwm hom. Ozone's negative charge yog delocalized hla ob kawg O, thaum tus nqi zoo yog nyob rau ntawm qhov chaw O .
Dab tsi delocalised electrons nyob hauv cov qauv hlau?
Hlau muaj cov qauv loj heev ntawm cov atoms teem rau hauv cov qauv tsis tu ncua. Cov electrons los ntawm cov plhaub sab nraud ntawm cov hlau atoms yog delocalised, thiab muaj kev ywj pheej txav mus los ntawm tag nrho cov qauv. Qhov kev sib koom ntawm delocalised electrons no ua rau muaj zog hlau sib txuas hlau hlau sib txuas hlau hlau muaj zog, yog li cov hlau tuaj yeem tuav cov qauv tsis tu ncua thiab feem ntau muaj cov ntsiab lus kub thiab kub.
