Thaum twg electrons txav los ntawm qib siab zog mus rau qis dua, photons raug tso tawm, thiab emissions kab tuaj yeem pom hauv spectrum . Kev nqus kab pom thaum electrons nqus photons thiab txav mus rau qib siab zog. Yog tias lub atom poob ib lossis ntau dua electrons , nws yog hu ua ion thiab hais tias yuav ionized.

Yog li ntawd, yuav ua li cas spectral kab tsim?

Raws li electrons dhia mus rau n = 2 orbit, lawv emit photons ntawm tej zaus (li no xim) uas yuav pom tau tias emission. kab hauv qhov pom ntawm em spectrum . Tus naj npawb ntawm spectral kab uas tau ua Nws yog loj heev muab qhov permutations ntawm atoms, molecules thiab orbital hloov tau.

Ib yam li ntawd, dab tsi tshwm sim rau ib qho hluav taws xob hauv lub atom los tsim cov kab spectral hauv ib qho emission spectrum? Ib emission kab yog ua los ntawm ib atom nyob rau hauv ib lub 'excited' lub zog---lub hluav taws xob tsis yog nyob rau hauv lub zog orbit tsawg npaum li sai tau. Nco ntsoov txoj cai #3! Nyob rau hauv thiaj li yuav mus rau ib tug qis zog orbit, lub hluav taws xob yuav tsum poob lub zog ntawm ib qho nyiaj tshwj xeeb.

Tom qab, lo lus nug yog, dab tsi ua rau cov kab spectral tshwm?

Lub xub ntiag ntawm spectral kab tau piav qhia los ntawm quantum mechanics nyob rau hauv cov nqe lus ntawm lub zog theem ntawm atoms, ions thiab molecules. Emission kab tshwm sim Thaum cov electrons ntawm ib qho atom zoo siab, lub ntsiab lus lossis cov molecule txav ntawm qib zog, rov qab los rau hauv av.

Vim li cas cov ntsiab lus muaj cov kab sib txawv?

Emission spectroscopy. Txhua keeb muaj ib txawv atomic spectrum . Kev tsim tawm ntawm kab spectra los ntawm cov atom ntawm ib keeb qhia tias lub atom tuaj yeem tawg tsuas yog qee lub zog xwb. Qhov no ua rau kev txiav txim siab uas khi electrons tsis tuaj yeem muaj tsuas yog ib qho ntawm lub zog tab sis tsuas yog ib qho ntawm lub zog xwb.
