Qhov sib txawv tseem ceeb ntawm lub zog ionization thiab lub zog khi yog tias lub zog ionization yog qhov tsawg kawg nkaus ntawm lub zog xav tau los tshem tawm cov hluav taws xob xoob feem ntau ntawm ib qho kev sib cais nruab nrab ntawm cov pa roj carbon monoxide lossis molecule whereas binding zog yog qhov tsawg kawg nkaus ntawm lub zog xav tau. kom tshem tau ib tug hais los ntawm ib tug hais.
Ionization zog thiab khi lub zog ntawm cov tshuaj lom neeg yog ob lub ntsiab lus sib txawv, piav txog ob qhov xwm txheej sib txawv. Cia peb tham ntxiv txog cov ntsiab lus hauv qab no hauv kab lus no.
Ionization Zog yog dab tsi?
Ionization lub zog yog qhov tsawg kawg nkaus ntawm lub zog xav tau los rub tawm cov hluav taws xob xoob feem ntau ntawm ib qho nruab nrab tsis muaj roj atom lossis cov molecule. Peb tuaj yeem txheeb xyuas qhov tshuaj tiv thaiv ionization raws li hauv qab no:
X(g) + zog ⟶ X+(g) + e –
Nyob rau hauv qhov sib npaug no, X yog ib qho atom lossis molecule thaum X+ yog cov ion nrog cov xoob khi electron tshem tawm ntawm lub atom lossis molecule thaum e–yog qhov tshem tawm electron. Feem ntau, qhov no yog txheej txheem endothermic. Feem ntau, nyob deb ntawm cov hluav taws xob sab nraud yog los ntawm cov atomic nucleus, txo lub zog ionization thiab rov ua dua.
Daim duab 01: Thawj Ionization Zog tiam sis nyob rau hauv Lub Sijhawm Table ntawm Cov Ntsiab Lus
Nyob rau hauv lub cev chemistry, ionization zog yog qhia nyob rau hauv lub chav tsev ntawm electronvolts (eV). Txawm li cas los xij, chav tsev no feem ntau tsis siv hauv cov ntsiab lus tshuaj vim tias peb suav cov nqi "ib mole" units. Yog li, chav ntsuas ntawm ionization zog yog kilojoules ib mole (kJ / mol). Tsis tas li ntawd, muaj cov kev hloov pauv ntawm lub zog ionization nyob rau hauv lub sij hawm ntev; ionization zog feem ntau nce ntawm sab laug mus rau sab xis nyob rau hauv ib lub sij hawm muab, thiab ionization zog feem ntau txo los ntawm sab saum toj mus rau hauv qab nyob rau hauv ib pab pawg neeg.
Yuav ua li cas khi zog?
Kev khi lub zog yog qhov tsawg kawg nkaus ntawm lub zog yuav tsum tau tshem tawm ib qho ntawm cov kab ke. Peb kuj tuaj yeem piav qhia nws yog qhov tsawg tshaj plaws ntawm lub zog uas yuav tsum tau ua kom tshem tawm cov txheej txheem ntawm cov khoom mus rau hauv ib qho chaw. Txawm li cas los xij, nyob rau hauv nuclear physics, lub sij hawm sib cais zog yog siv es tsis yog lub sij hawm binding zog. Feem ntau, lub kaw lus khi yog nyob rau theem qis zog dua li nws cov khoom siv tsis raug.
Daim duab 02: Kev khi lub zog nkhaus rau cov tshuaj sib txawv
Muaj ntau hom kev khi zog: electron binding zog lossis lub zog ionization, atomic binding zog, bond dissociation zog, nuclear binding zog, gravitational binding zog, thiab lwm yam.
Qhov txawv ntawm Ionization zog thiab khi zog yog dab tsi?
Ionization zog yog ib hom kev khi zog. Qhov sib txawv tseem ceeb ntawm ionization zog thiab khi zog yog tias lub zog ionization yog qhov tsawg kawg nkaus ntawm lub zog xav tau los tshem tawm cov hluav taws xob feem ntau xoob ntawm ib qho kev sib cais nruab nrab ntawm cov pa roj carbon monoxide lossis cov molecule whereas lub zog khi yog qhov tsawg kawg nkaus ntawm lub zog yuav tsum tau tshem tawm. particle los ntawm ib qhov system ntawm hais.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm ionization zog thiab khi zog.
Summary – Ionization Zog vs Binding zog
Ionization zog yog ib hom kev khi zog. Qhov sib txawv tseem ceeb ntawm lub zog ionization thiab kev sib khi zog yog tias lub zog ionization yog qhov tsawg kawg nkaus ntawm lub zog xav tau los tshem tawm cov feem ntau xoob khi electron ntawm ib qho kev sib cais nruab nrab gaseous atom los yog molecule whereas binding zog yog qhov tsawg kawg nkaus ntawm lub zog yuav tsum tau tshem tawm ib tug hais los ntawm. ib qhov system ntawm hais.
