Electrons belongs rau thawj tiam ntawm lub lepton cov tsev neeg particle, thiab feem ntau xav tias yog cov khoom siv hluav taws xob vim lawv tsis paub cov khoom lossis cov khoom siv. Cov electron muaj qhov loj uas yog kwv yees li 1/1836 ntawm qhov proton.
Tsis tas li ntawd, lub tshuab hluav taws xob yog dab tsi?
yog, electrons yog ua nce ntawm tus nqi, huab hwm coj, thiab angular momentum. Ua ib hluav taws xob , ncav cuag thoob plaws lub teb hluav taws xob (uas yog txwv tsis pub zaum ntawd) thiab qhia txaus wiggle los tsim −1.602 × 10−19 coulombs ntawm tus nqi.
Ib yam li ntawd, puas yog ib qho hluav taws xob yog lub cev? Cov hluav taws xob yog point particle. Thaum ib hluav taws xob yog coj zoo li nthwv dej, nws tuaj yeem muaj txhua hom duab, tsuav yog nws cov duab ua raws cov hluav taws xob yoj sib npaug. Ib electron cov yoj sib npaug, thiab yog li ntawd nws cov duab, yog ib txoj haujlwm ntawm nws lub zog thiab cov duab ntawm lub peev xwm zoo cuab nws.
Kuj tseem paub, dab tsi tus nqi hluav taws xob muaj?
Electrons muaj ib electric nqi ntawm −1, uas yog sib npaug tab sis opposite rau cov nqi ntawm proton, uas yog +1.
Puas yog electrons tiag tiag?
Hluav taws xob yog yam nthuav. Tab sis raws li quantum khoom, electrons tsis yog cov khoom . Lawv tsis orbit lub nucleus ntawm lub atom, tab sis nyob ib puag ncig nws nyob rau hauv ib tug fuzzy quantum huab. Hluav taws xob tuaj yeem nthuav tawm particle -zoo li tus cwj pwm hauv qee qhov kev sim, tab sis lawv tsis yog ib qho nyuaj, cov khoom zoo li peb xav cov khoom.

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
Qhov txawv ntawm qhov loj ntawm ib tug proton thiab qhov loj ntawm ib tug electron yog dab tsi?
Protons thiab neutrons muaj kwv yees li qub, tab sis lawv yog ob qho tib si loj dua li cov hluav taws xob (kwv yees li 2,000 npaug loj li electron). Tus nqi zoo ntawm ib qho proton yog sib npaug hauv qhov loj rau qhov tsis zoo ntawm tus electron
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog meant los ntawm yoj particle xwm ntawm lub teeb?
Hauv physics thiab chemistry, nthwv dej-particle dual tuav lub teeb thiab teeb meem pom cov khoom ntawm ob lub nthwv dej thiab cov khoom. Lub tswv yim ntawm duality yog rooted nyob rau hauv kev sib cav txog qhov xwm ntawm lub teeb thiab teeb meem yos rov qab mus rau 1600s, thaum sib tw theories ntawm lub teeb tau npaj los ntawm Christiaan Huygens thiab Isaac Newton
Dab tsi yog txhais los ntawm lub sij hawm dissociation thiab dab tsi yog ib qho piv txwv ntawm cov khoom uas dissociates?
Dissociation, nyob rau hauv chemistry, sib cais ntawm ib yam khoom mus rau hauv atoms los yog ions. Thermal dissociation tshwm sim ntawm qhov kub thiab txias. Piv txwv li, hydrogen molecules (H 2) dissociate rau hauv atoms (H) ntawm kub heev; ntawm 5,000 ° K txog 95% ntawm cov molecules hauv cov qauv ntawm hydrogen yog dissociated rau hauv atoms
