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.

Yog delocalized electrons zoo lossis tsis zoo?

Kev siv hluav taws xob. Delocalized electrons kuj muaj nyob rau hauv cov qauv ntawm cov khoom hlau. Cov qauv hlau muaj qhov sib npaug zoo ions (cations) hauv "hiav txwv" ntawm delocalized electrons. Qhov no txhais tau hais tias cov electrons muaj kev ywj pheej txav mus thoob plaws hauv cov qauv, thiab ua rau muaj zog xws li conductivity.

Yog delocalized electrons zoo?

Nyob hauv cov hlau, cov electrons tawm hauv lub plhaub sab nraud ntawm cov hlau atoms, tsim zoo hlau ions thiab ' hiav txwv' ntawm delocalised electrons.

txhais li cas thaum electrons raug delocalized?

Electron delocalization (delocalization): Kev faib tawm ntawm electron ceev tshaj qhov chaw ruaj xws li ib atom, ib khub, lossis covalent daim ntawv cog lus ntawm resonance lossis inductive teebmeem.

Dab tsi yog delocalized electrons los ntawm?

Txij li thaum conjugation coj cov hluav taws xob delocalization, nws ua raws li qhov ntau ntawm cov kab ke sib txuas, qhov ruaj khov ntawm cov molecule (piv txwv li qis dua nws lub peev xwm zog). Yog tias muaj qhov zoo lossis qhov tsis zoo, lawv kuj kis tau los ntawm resonance.
