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.

Ib yam li ntawd, koj ua li cas txiav txim siab qhov emission spectra element?

Hauv emission spectrum , cov kab ci ntsa iab yuav qhia txog qhov sib txawv ntawm lub zog ntawm cov qib cov ntsiab lus , qhov twg hauv kev nqus spectrum , cov kab yuav tsaus. Los ntawm kev saib cov qauv ntawm cov kab, cov kws tshawb fawb tuaj yeem txheeb xyuas cov qib zog ntawm cov cov ntsiab lus hauv tus qauv.

Kuj Paub, kab spectra muab pov thawj li cas? YUAV UA LI CAS ua tus kab emission spectrum ntawm hydrogen muab pov thawj rau lub hav zoov ntawm electrons nyob rau hauv discrete zog theem, uas converge ntawm ntau zog? Xws li ib tug electron yuav emit photons ntawm qee qhov wavelength thaum lawv rov qab mus rau lawv cov theem ntawm keeb kwm.

Ua raws li qhov no hauv kev txiav txim siab, cov pov thawj dab tsi ua kab emission spectra muab rau qhov muaj nyob ntawm qib zog hauv atoms?

Qhov tseeb tias a kab spectrum tau pom - thiab tsis yog ib qho txuas ntxiv - qhia tau hais tias tsuas yog tshwj xeeb zog kev hloov pauv tuaj yeem ua tau hauv ib qho atom . Qhov no muaj zog pov thawj rau cov muaj nyob ntawm qib zog . Lub photon ntawm lub teeb tso tawm yog ntawm ib qho zaus thiab yuav tsum tsis txhob nyob rau hauv qhov pom ntau yam.

Cov pov thawj dab tsi txhawb nqa Bohr tus qauv?

Bohr Qauv thiab Atomic Spectra The pov thawj siv rau kev txhawb nqa tus Bohr qauv 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.
