Cov ntaub ntawv uas tso cai ntau electrons txav ywj siab yog hu ua conductors thiab cov ntaub ntawv uas tso cai ob peb dawb electrons txav yog hu ua insulators. Txhua yam teeb meem yog ua los ntawm atoms uas muaj hluav taws xob. Yog li ntawd, lawv muaj cov nqi hluav taws xob.
Yuav Ua Li Cas Hluav Taws Xob ua haujlwm ?
| 1. | Thaum tshav kub kub thiab lub zog |

Ib yam li ntawd, koj yuav nug, dab tsi ua rau cov electrons txav mus los?
Thaum ib tug zoo charged khoom muab tso rau ntawm ib tug conductor electrons yog attracted tus kwv. Thaum siv hluav taws xob voltage, ib qho hluav taws xob hauv cov hlau ua rau lub zog ntawm lub electrons , ua rau lawv hloov ntawm ib kawg mus rau lwm qhov kawg ntawm tus neeg xyuas pib. Hluav taws xob yuav txav mus rau sab zoo.
Dab tsi yog hluav taws xob tsis tuaj yeem hla? Cov ntaub ntawv uas tsis tso cai hluav taws xob rau hla yooj yim dhau lawv hu ua insulators. Roj hmab, iav, yas, thiab ntaub yog cov neeg ua haujlwm tsis zoo hluav taws xob . Qhov no yog vim li cas cov hlua hluav taws xob tau npog hauv cov roj hmab, yas, lossis ntaub.
Ib yam li ntawd, tib neeg nug, ua li cas electrons txav hauv ib lub voj voog?
Cov Lus Qhia Tam Sim No Cov Lus Qhia uas nqa cov nqi los ntawm cov xov hlau hauv a Circuit Court yog mobile electrons . Kev taw qhia hluav taws xob hauv ib Circuit Court yog los ntawm kev txhais cov kev taw qhia uas cov nqi kuaj zoo raug thawb. Yog li ntawd, cov no negatively them electrons txav nyob rau hauv cov kev taw qhia opposite lub teb hluav taws xob.
Yuav ua li cas rau electrons thaum siv hluav taws xob?
Circuits tsis tsim, rhuav tshem, siv, lossis poob electrons . Lawv tsuas nqa cov electrons nyob ib ncig ntawm lub voj voog. Hluav taws xob ib txwm muaj nyob rau hauv Circuit Court raws li ib feem ntawm cov atom thiab molecules uas ua rau lub circuit. Lub zog hluav taws xob uas xa tawm yog qhov tshwm sim ntawm qhov electrons txav los ntawm Circuit Court.

Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Dab tsi yog peb txoj cai tswj hwm kev sau ntawm atomic orbitals los ntawm electrons?
Thaum muab cov electrons rau orbitals, peb yuav tsum ua raws li peb txoj cai: Aufbau Txoj Cai, Txoj Cai Pov Hwm Pov Hwm Pov Hwm, thiab Hund Txoj Cai
Dab tsi ntawm cov khoom hauv qab no ntawm dej tso cai rau kab taug kev ntawm dej?
Nws tsis yog tsuas yog dej-cua saum npoo nro uas tso cai rau cov kab taug kev hauv dej. Nws yog kev sib xyaw ua ke ntawm ob txhais ceg tsis raug wetted thiab nto nro. Ob txhais ceg ntawm dej striders yog hydrophobic. Cov dej molecules muaj zog heev attracted rau ib leeg
Tus kws tshawb fawb twg txiav txim siab tias electrons taug kev ntawm txoj kev tshwj xeeb?
Atomic qauv Bohr qauv qhia lub atom raws li ib tug me me, zoo nqi nucleus ncig los ntawm orbiting electrons. Bohr yog thawj zaug nrhiav pom tias cov hluav taws xob taug kev nyob rau hauv nyias lub orbits nyob ib ncig ntawm lub nucleus thiab hais tias cov xov tooj ntawm electrons nyob rau hauv lub orbit sab nrauv txiav txim lub zog ntawm ib lub caij
Dab tsi yog qhov txawv ntawm cov tswv yim ua haujlwm thiab cov khoom tso tawm ua haujlwm?
Input ua hauj lwm yog ua hauj lwm ua nyob rau hauv ib tug machineas lub input quab yuam ua los ntawm lub input nrug.Qhov no yog nyob rau hauv sib piv rau cov zis ua hauj lwm uas yog ib tug quab yuam uas yog siv los ntawm lub cev los yog system rau lwm yam. Output work yog qhov ua haujlwm los ntawm lub tshuab ua haujlwm raws li cov zis tawm dag zog los ntawm qhov tso tawm qhov deb
