Qhov sib txawv tseem ceeb ntawm hydrogen thiab helium emission spectra yog tias helium emission spectrum (plu. spectra) muaj ntau kab ntau dua li ntawm hydrogen emission spectrum (plu. spectra).
Cov emission spectrum ntawm cov tshuaj lom neeg los yog cov khoom sib xyaw yog cov kab uas sawv cev rau lub wavelengths ntawm electromagnetic hluav taws xob tawm los ntawm cov khoom siv tshuaj thaum lub sij hawm hloov ntawm ib qho hluav taws xob los ntawm qib siab mus rau qib qis zog.
Hydrogen Emission Spectra yog dab tsi?
Lub hydrogen emission spectrum yog ib qho spectrum uas tsim los ntawm emission ntawm lub teeb los ntawm hydrogen atoms nyob rau hauv lub xeev zoo siab. Nyob ntawd, thaum peb hla lub teeb dawb ntawm ib qho piv txwv ntawm hydrogen gas, ces cov atoms nqus lub zog. Tom qab ntawd, cov hluav taws xob hauv hydrogen atom tau txais kev zoo siab mus rau qib siab zog. Txawm li cas los xij, txij li thaum nyob hauv qib siab zog tsis ruaj khov, cov electrons zoo li rov qab los rau hauv av (theem lub zog uas lawv muaj yav dhau los) emitting photon li electromagnetic hluav taws xob uas muaj lub zog sib npaug ntawm lub zog sib txawv ntawm cov siab dua thiab qis zog.

Ntxiv mus, tus nqi ntawm lub zog ntawm txhua qib zog yog tus nqi ruaj khov. Yog li ntawd, kev hloov pauv yuav ib txwm tsim cov photon nrog tib lub zog. Peb tuaj yeem soj ntsuam qhov emission spectrum li xim xim ntawm keeb kwm yav dhau dub. Txawm li cas los xij, cov kab uas peb tuaj yeem pom ntawm no tsawg dua li ntawm helium emission spectrum.
Helium Emission Spectra yog dab tsi?
Lub helium emission spectrum yog ib qho spectrum uas tsim los ntawm emission ntawm lub teeb los ntawm helium atoms nyob rau hauv zoo siab lub xeev. Nws muaj ntau kab hauv nws piv rau hydrogen emission spectrum. Nws yog feem ntau vim hais tias lub helium atom muaj ntau cov electrons tshaj li hydrogen atom. Yog li ntawd, ntau electrons tau zoo siab thaum peb dhau lub teeb teeb dawb los ntawm cov qauv helium, thiab nws ua rau emission ntawm ntau spectral kab.

Tsis zoo li hauv hydrogen, muaj cov hluav taws xob-electron repulsions thiab sib txawv nuclei-electron attractions hauv helium atom. Yog li ntawd, txawv spectra (sib txawv ntawm hydrogen) los nrog txawv wavelengths rau helium atom.
Qhov txawv ntawm Hydrogen thiab Helium Emission Spectra yog dab tsi?
Lub hydrogen emission spectrum yog ib qho spectrum uas tsim los ntawm emission ntawm lub teeb los ntawm hydrogen atoms nyob rau hauv lub xeev zoo siab. Ntawm qhov tod tes, helium emission spectrum yog ib qho spectrum uas tsim los ntawm emission ntawm lub teeb los ntawm helium atoms nyob rau hauv lub xeev siab. Thiab, qhov sib txawv tseem ceeb ntawm hydrogen thiab helium emission spectra yog tias helium emission spectrum muaj ntau kab ntau dua li ntawm hydrogen emission spectrum. Nws feem ntau yog vim hydrogen muaj ib qho hluav taws xob ib atom thaum helium muaj ob lub electrons ib atom.
Tsis tas li ntawd, qhov sib txawv tseem ceeb ntawm hydrogen thiab helium emission spectra yog tias tsis muaj kev cuam tshuam los ntawm electron-electron repulsions ntawm hydrogen emission spectra vim muaj ib qho hluav taws xob hauv hydrogen atom hos electron-electron repulsions cuam tshuam rau helium. emission spectra vim muaj ob lub electrons.
Summary – Hydrogen vs Helium Emission Spectra
Cov emission spectrum yog ib qho spectrum uas qhia cov kab ntawm cov keeb kwm dub. Ntawm no, lub emission ntawm lub teeb los ntawm hydrogen atoms nyob rau hauv lub xeev zoo siab ua rau cov hydrogen emission spectrum. Txawm li cas los xij, qhov emission ntawm lub teeb los ntawm helium atoms hauv cov xeev zoo siab ua rau helium emission spectrum. Qhov sib txawv tseem ceeb ntawm hydrogen thiab helium emission spectra yog tias helium emission spectrum muaj ntau kab ntau dua li ntawm hydrogen emission spectrum.
