Txheej txheem. Raws li cov txiaj ntsig kev sim, nws muaj kev nyab xeeb xaus uas ntau yam khoom tso tawm xim sib txawv thaum raug rau a nplaim taws , thiab muaj cov xim no yog pov thawj ntawm atomic emission. Tsis tas li ntawd, muaj kev sib raug zoo ntawm lub wavelength ntawm ib lub caij thiab cov xim nws emits.
Tib neeg kuj nug, lub hom phiaj ntawm kev xeem nplaim hluav taws yog dab tsi?
Cov nplaim taws kuaj yog siv los txiav txim qhov pom ntawm tus kheej ntawm cov hlau tsis paub ntawm cov ntsev ionic raws li tus yam ntxwv xim ntsev tig lub nplaim taws ntawm ib tug bunsen burner.
Ib yam li ntawd, qhov ntsuas nplaim taws ua haujlwm li cas? Kev sim nplaim taws . Kev sim nplaim taws muaj txiaj ntsig zoo vim tias cov roj excitations tsim cov kab kos npe emission spectrum rau ib lub caij. Thaum cov atoms ntawm cov pa roj los yog vapor zoo siab, piv txwv li los ntawm cua sov lossis los ntawm kev siv hluav taws xob, lawv cov electrons tuaj yeem txav los ntawm lawv lub xeev hauv av mus rau qib siab dua.
Yog li ntawd, vim li cas cov nplaim taws tseem ceeb?
Kev sim nplaim taws pab cov kws tshawb fawb thiab cov tub ntxhais kawm vim tias lawv tuaj yeem tshawb pom qee yam hauv cov ntsiab lus tsis paub. Qhov kev paub no muab ob qho tib si lub tswv yim zoo dua ntawm hom kev sib xyaw ua ke, thiab nws tuaj yeem qhia tau tias cov compound muaj metalloid lossis hlau ions hauv nws.
Vim li cas cov xim emissions thaum lub sij hawm sim nplaim taws?
Cov xim pom thaum lub sij hawm xeem nplaim taws tshwm sim los ntawm kev zoo siab ntawm cov electrons tshwm sim los ntawm qhov kub thiab txias. Cov electrons "dhia" los ntawm lawv lub xeev hauv av mus rau qib siab zog. Cov xim tawm los ntawm cov atoms loj dua yog qis zog dua lub teeb tso tawm los ntawm me me atoms.

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Koj tuaj yeem txheeb xyuas cov hlau li cas los ntawm kev ntsuas nplaim taws?
Chemists siv tib lub hauv paus ntsiab lus los txiav txim seb tus kheej ntawm cov hlau tsis paub siv qhov ntsuas nplaim taws. Thaum kuaj nplaim hluav taws, chemists coj ib qho hlau tsis paub thiab muab tso rau hauv qab nplaim taws. Cov nplaim taws yuav tig xim sib txawv raws li cov hlau nyob hauv cov khoom. Cov kws tshawb fawb tuaj yeem txheeb xyuas lawv cov khoom tsis paub
Cov kab hluav taws xob hluav taws xob pib thiab xaus qhov twg?
Cov cai hauv qab no siv rau cov kab hluav taws xob: Cov kab pib thiab xaus nkaus xwb (pib ntawm + nqi, xaus ntawm - nqi) lossis ntawm Infinity. Cov kab yog nyob ze ua ke qhov twg lub teb muaj zog dua. Cov nqi loj dua muaj ntau kab kab pib lossis xaus rau lawv
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
