Yuav kho qhov teeb meem stability, Bohr hloov kho lub Rutherford qauv los ntawm kev xav kom cov electrons txav hauv orbits ntawm qhov loj thiab lub zog. Lub zog ntawm ib qho hluav taws xob nyob ntawm qhov loj ntawm lub orbit thiab qis dua rau cov orbits me. Radiation tuaj yeem tshwm sim tsuas yog thaum lub electron dhia ntawm ib lub orbit mus rau lwm qhov.

Tsis tas li ntawd, Bohr tus qauv txawv li cas rau Rutherford's?

Rutherford piav txog lub atom uas muaj ib tug me me zoo huab hwm coj ncig los ntawm ib tug huab ntawm tsis zoo electrons. Bohr xav tias electrons orbited lub nucleus nyob rau hauv quantised orbits. Bohr ua rau ntawm Rutherford tus qauv ntawm atom. Yog li nws tsis muaj peev xwm rau electrons los tuav ib theem zog xwb.

Bohr ntsib teeb meem dab tsi nrog Rutherford txoj kev xav? Bohr circumvented qhov teeb meem nrog Rutherford tus Atomic Model los ntawm kev tawm tswv yim tias electrons "dhia" ntawm orbits thaum lawv nce lossis poob zog. Yog li, lawv tsis muaj nyob hauv ib lub xeev nyob nruab nrab ntawm lub orbits. Tsis zoo them electrons orbit ib tug zoo nqi nucleus nyob rau hauv orbits nrog teem zog theem.

Yog li ntawd, Bohr tau hloov kho Rutherford lub hnub ci qauv qauv ntawm lub atom li cas Cov kev txwv ntawm Bohr tus qauv yog dab tsi?

Bohr txhim kho Rutherford tus qauv atomic los ntawm kev tawm tswv yim tias electrons tau mus ncig hauv lub voj voog ncig nrog cov qib zog tshwj xeeb. Kev piav qhia: Rutherford xav tias electrons ncig lub nucleus zoo li cov ntiaj chaw nyob ib ncig ntawm lub hnub. Thaum hlau atom yog rhuab, nws absorbs zog thiab cov electrons dhia mus rau ntau zog zog.

Bohr tau hloov pauv dab tsi los txhawb peb txoj kev nkag siab ntawm atom?

Xyoo 1913, Niels Bohr npaj ib txoj kev xav rau hydrogen atom raws li quantum txoj kev xav hais tias lub zog tsuas yog hloov mus rau hauv qee qhov kev txiav txim zoo. Cov hluav taws xob yuav tsum txav mus ib puag ncig lub nucleus tab sis tsuas yog nyob rau hauv lub orbits. Thaum dhia ntawm ib lub orbit mus rau lwm qhov nrog qis zog, lub teeb quantum yog emissions.
