Yog li txhua yam electron configuration hauv qhov twg tus kawg hluav taws xob (dua, tus valence hluav taws xob ) yog in a siab zog orbital, lub caij no yog hais tias nyob rau hauv ib tug zoo siab xeev . Piv txwv li, yog peb saib hauv av xeev ( electrons hauv tus lub zog qis tshaj muaj orbital) ntawm cov pa oxygen, electron configuration yog 1s22p4.

Kuj paub, nws txhais li cas los ntawm av xeev electron configuration?

Cov ground state electron configuration yog kev npaj ntawm electrons nyob ib ncig ntawm lub nucleus ntawm lub atom nrog qis zog. Cov electrons occupying lub orbitals ntawm txawv zog theem ib txwm poob mus rau qhov qis zog xeev los yog hauv av xeev.

Ib sab saum toj no, dab tsi yog qhov kev teeb tsa hluav taws xob ntawm Mn atom hauv av? Cov ground state electron configuration ntawm hauv av xeev gaseous nruab nrab manganese yog [Ar]. 3d ib5. 4s ib2 thiab lub sij hawm cim yog 6S5/2.

Yog li ntawd, tus sawv cev twg yog nyob rau hauv lub xeev configuration?

A hauv av - xeev atom yog ib qho atom uas tag nrho lub zog ntawm electrons tsis tuaj yeem txo qis los ntawm kev xa mus ib los yog ntau dua electrons rau txawv orbitals. Ntawd yog, hauv a hauv av - xeev atom, tag nrho cov electrons yog nyob rau hauv qis tshaj tau lub zog. Piv txwv li: Xav txog cov pa roj carbon atom uas nws electron configuration yog cov hauv qab no.

Hund txoj cai yog dab tsi?

Hund txoj cai . Hund txoj cai : Txhua lub orbital nyob rau hauv lub subshell yog singly nyob nrog ib tug electron ua ntej ib qho orbital yog ob zaug nyob, thiab tag nrho cov electrons nyob rau hauv singly occupied orbitals muaj tib lub kiv.
