Lub xub ntiag ntawm tsuas yog qee cov kab hauv atomic spectrum txhais tau tias ib hluav taws xob muaj peev xwm tsuas yog txais yuav ib co discrete zog theem (lub zog yog quantized); li no lub tswv yim ntawm quantum plhaub . Lub photon zaus absorbed los yog tso tawm los ntawm ib qho atom yog kho los ntawm qhov sib txawv ntawm lub zog theem ntawm lub orbits.
Hais txog qhov no, Bohr tus qauv account li cas rau emission spectra ntawm atoms?
Bohr tus qauv ntawm hydrogen atom tau piav qhia meej rau nws pom emission spectrum . Cov hluav taws xob tuaj yeem txav los ntawm ib lub orbit mus rau lwm qhov los ntawm kev nqus lossis emitting zog, ua rau muaj tus yam ntxwv spectrum.
Cov pov thawj dab tsi txhawb nqa Bohr qauv? Bohr Qauv thiab Atomic Spectra The pov thawj siv rau txhawb nqa tus qauv Bohr tuaj ntawm atomic spectra. Bohr qhia tias ib qho atomic spectrum yog tsim thaum cov electrons nyob rau hauv ib qho atom txav ntawm qib zog.
Hais txog qhov no, dab tsi pov thawj muaj rau electrons hauv plhaub?
Ionization zog - cov pov thawj rau plhaub thiab sub- plhaub Ionization zog yog ib ntsuas ntawm tus lub zog xav tau los tshem tawm electrons los ntawm atoms. Raws li electrons yog tsis zoo them thiab protons nyob rau hauv tus nucleus raug them zoo, nyob ntawd yuav yog ib tug attraction ntawm lawv.
Koj pom qhov emission spectrum li cas?
Lub frequencies ntawm lub teeb uas ib tug atom yuav emit yog nyob ntawm lub xeev cov electrons tuaj yeem nyob rau hauv. Thaum zoo siab, ib tug electron txav mus rau lub zog siab dua los yog orbital. Thaum lub electron poob rov qab mus rau hauv av theem, lub teeb yog tso tawm.

Koj ua pov thawj li cas cov kab yog sib npaug hauv cov ntawv pov thawj?
Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug
Dab tsi pov thawj siv cov duab ntawm lub dav hlau sib koom ua pov thawj cov khoom geometric?
Cov ntaub ntawv pov thawj uas siv cov duab ntawm lub dav hlau sib koom ua pov thawj geometric zog yog hu ua trigonometric
Yuav ua li cas yog ib qho atomic emission spectra txawv ntawm ib tug nruam spectra?
Nruam spectrum: ib qho spectrum uas muaj tag nrho cov wavelengths uas tsis muaj qhov sib txawv ntawm ntau yam. Emission spectrum: Thaum lub electron nyob rau hauv lub xeev zoo siab tsiv mus rau qis zog theem, nws emits ib tug npaum li cas ntawm lub zog li photons. Lub spectrum rau qhov kev hloov no muaj cov kab vim hais tias cov qib zog yog quantized
Yuav ua li cas yog emission spectra pov thawj rau electron plhaub?
Lub xub ntiag ntawm tsuas yog qee cov kab hauv atomic spectra txhais tau hais tias ib qho hluav taws xob tsuas tuaj yeem txais qee qhov kev txiav txim siab lub zog (lub zog yog quantized); li no lub tswv yim ntawm quantum shells. Cov photon zaus absorbed los yog emitted los ntawm ib tug atom yog tsau los ntawm qhov sib txawv ntawm lub zog theem ntawm lub orbits
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
