Thaum ib hluav taws xob ib ntus occupies ib lub zog lub xeev siab tshaj nws hauv av xeev, nws yog nyob rau hauv ib tug zoo siab xeev. Ib hluav taws xob ua tau ua zoo siab yog tias nws tau txais lub zog ntxiv, xws li yog tias nws nqus cov photon, lossis pob ntawv ntawm lub teeb, lossis sib tsoo nrog cov atom los yog cov khoom nyob ze.
Ib yam li ib tug yuav nug, ua li cas electrons tau txais kev zoo siab?
Cov hluav taws xob tau zoo siab thaum lawv nqus cov photons los yog cov khoom ntawm lub teeb. Nyob ntawd yog tshwj xeeb zog sib txawv ntawm txawv plhaub ntawm electrons . Yog li ib hluav taws xob yog muab qhov xav tau ntawm lub zog dhia los ntawm nws lub xeev hauv av mus rau lub xeev siab dua, yuav tau zoo siab.
Ib sab saum toj no, vim li cas electrons zoo siab los ntawm tshav kub? Thaum lub electrons hauv atom yog zoo siab , piv txwv li yog cua sov , lub zog ntxiv pushes lub electrons rau siab zog orbitals. Thaum lub electrons poob rov qab thiab tawm ntawm zoo siab lub xeev, lub zog yog re-emitted nyob rau hauv daim ntawv ntawm ib tug photon.
Kuj paub, dab tsi yog ob txoj kev electrons tuaj yeem txaus siab?
Electrons tau kuj be zoo siab los ntawm hluav taws xob excitation, qhov twg tus thawj hluav taws xob absorbs lub zog ntawm lwm tus, muaj zog hluav taws xob . Txoj kev yooj yim tshaj plaws yog kom sov cov qauv mus rau qhov kub thiab txias. Lub zog thermal tsim kev sib tsoo ntawm cov qauv atoms ua rau lub atom electrons ua zoo siab.
Thaum tshav kub kub excite electrons?
Ib txoj kev mus zoo siab ib hluav taws xob Zoo li koj hais, yog los ntawm absorbing photons ntawm lub teeb. Thermal zog ua tau kuj tsa lub hluav taws xob mus rau lub xeev siab zog, uas yog dab tsi tshwm sim nyob rau hauv koj cov hlau ntsev hlawv sim. Qhov ua rau excitation yog qhov kub , thiab lub teeb yog emitted thaum lub hluav taws xob rov qab los rau hauv av xeev.

Qhov twg yog qhov zoo siab electrons ntws los ntawm photosystem II pib los ntawm? Photosystem II strips electrons los ntawm H2O. Ib tus kab mob cog tshiab uas tau txheeb xyuas tau kis thiab tua nws tus tswv los ntawm kev ntxig cov kab protein loj rau hauv thylakoid daim nyias nyias, tsim qhov chaw mus tas li
Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Yuav ua li cas koj thiaj nrhiav tau qhov siab tshaj plaws ntawm electrons?
Ntxiv cov Electrons rau TxhuaFullOrbital Ntxiv cov khoom siv hluav taws xob ntau tshaj plaws uas txhua lub orbital tuaj yeem tuav tau. Sau tus lej no rau yav tom ntej siv.Piv txwv, thawj lub orbital tuaj yeem tuav ob lub electrons; thib ob, yim; thiab qhov thib peb, 18. Yog li ntawd lub threeorbitalscombined tuaj yeem tuav 28 electrons
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Koj yuav ua li cas thiaj paub tias kev sib raug zoo yog qhov zoo lossis tsis zoo?
Qhov zoo correlation coefficient txhais tau hais tias raws li tus nqi ntawm ib qho kev sib txawv nce, tus nqi ntawm lwm qhov sib txawv nce; raws li ib tug txo qhov qis dua. Qhov tsis zoo correlation coefficient qhia tau hais tias raws li ib qho kev sib txawv nce, qhov txo qis, thiab vice-versa
