Radial faib nkhaus muab ib lub tswv yim txog lub electron ceev ntawm a radial nyob deb ntawm lub nucleus. Tus nqi ntawm 4πr2ψ2 ( radial probability ntom muaj nuj nqi ) ua xoom ntawm qhov taw tes nodal, tseem hu ua a radial node. Qhov twg n = thawj tus lej quantum thiab l = azimuthal quantum tooj.

Tsis tas li ntawd, dab tsi yog radial probability faib?

Radial probability faib ntawm ib lub vojvoog muab yog lub qhov tshwm sim ib qhov deb uas qhov kev tshwm sim tshwm sim nyob rau hauv ib tug infinitesimally nyias kheej kheej plhaub ntawm lub vojvoog ntawd.

Ib yam li ntawd, yuav ua li cas faib curves? A qhov yuav faib yog ib qho kev ua haujlwm txheeb cais uas piav qhia txog txhua qhov muaj txiaj ntsig thiab qhov yuav tshwm sim uas qhov sib txawv ntawm qhov sib txawv tuaj yeem coj mus rau hauv qhov muab ntau yam. Cov xwm txheej no suav nrog kev faib tawm txhais tau tias (nruab nrab), tus qauv sib txawv, skewness, thiab kurtosis.

Hauv qhov no, qhov txawv ntawm qhov radial probability nkhaus rau 1s thiab 2s orbital yog dab tsi?

Cov Qhov tshwm sim radial kev faib tawm nkhaus rau 2 s orbit qhia tau hais tias ob lub maxima, ib qho me me nyob ze ntawm lub nucleus thiab loj dua ib qho ntawm qhov loj dua. Li no 1 s orbit yog ze rau lub nucleus hauv kev sib piv rau 2s ib thiab 2p ov ov . Lub vojvoog ntawm qhov siab tshaj plaws qhov tshwm sim ntawm 2 s orbit yog ntau dua 2 p oib.

Lub vojvoog ntawm qhov ua tau siab tshaj plaws yog dab tsi?

Tso tseg cov nqe lus tas mus li thiab noj cov derivative nrog rau r thiab teeb tsa nws sib npaug rau xoom muab qhov lub vojvoog rau Qhov siab tshaj plaws . Qhov zoo tshaj plaws lub vojvoog yog lub xeev hauv av lub vojvoog tau los ntawm Bohr txoj kev xav.
