Piv txwv li, Planck qhov tsis tu ncua tuaj yeem sau ua h=6.6x10-34 joule vib nas this. Siv Planck qhov tsis tu ncua, Bohr tau txais cov qauv tseeb rau qib zog ntawm hydrogen atom. Nws postulated tias lub angular momentum ntawm lub electron yog quantized - piv txwv li, nws muaj peev xwm tsuas muaj discrete qhov tseem ceeb.
Leej twg hais tias lub atom yog quantized?
Bohr yog thawj tus paub qhov no los ntawm kev sib koom ua ke lub tswv yim ntawm quantization rau hauv cov qauv hluav taws xob ntawm hydrogen atom, thiab nws muaj peev xwm piav qhia qhov emission spectra ntawm hydrogen li. zoo li lwm lub tshuab hluav taws xob.
Vim li cas angular momentum ntawm electron yog quantized?
Raws li Bohr tus qauv atomic, lub angular momentum ntawm electrons orbiting ncig lub nucleus yog quantized. Nws hais ntxiv tias electrons txav tsuas yog nyob rau hauv cov orbits qhov twg lub angular momentum ntawm ib tug electron yog ib tug ntau yam ntawm h/2.
Lub ntsiab lus ntawm lub zog ntawm lub zog ntawm lub zog hluav taws xob yog dab tsi?
Quantization ntawm angular momentum txhais tau hais tias lub vojvoog ntawm lub orbit thiab lub zog yuav raug suav nrog Bohr xav tias cov kab sib cais pom hauv spectrum ntawm hydrogen atom yog vim rau kev hloov ntawm ib qho hluav taws xob los ntawm ib qho kev tso cai orbit / lub zog mus rau lwm qhov.
Neil Bohr atomic qauv yog dab tsi?
Atomic qauv
Bohr qauv qhia lub atom raws li ib tug me me, zoo nqi nucleus ncig los ntawm orbiting electronsBohr yog thawj zaug nrhiav pom tias electrons mus txawv tebchaws. orbits nyob ib ncig ntawm lub nucleus thiab hais tias tus naj npawb ntawm electrons nyob rau hauv lub orbit txheej txiav txim lub zog ntawm ib lub caij.
