Hauv chemistry, tus thawj xibfwb qib zog ntawm ib tug electron hais txog lub plhaub los yog orbital nyob rau hauv uas lub electron nyob rau hauv lub atom lub nucleus. Qhov no qib yog denoted los ntawm tus thawj xib fwb quantum tooj n. Thawj lub caij nyob rau hauv ib lub sij hawm ntawm lub sij hawm lub sij hawm qhia ib tug tshiab tus thawj xib fwb qib zog.

Hauv qhov no, muaj pes tsawg lub zog tseem ceeb muaj?

Tus naj npawb ntawm lub zog nyob rau hauv txhua lub sij hawm Lub atoms nyob rau hauv thawj lub sij hawm muaj electrons nyob rau hauv 1 qib zog. Lub atoms nyob rau hauv lub sij hawm thib ob muaj electrons nyob rau hauv 2 qib zog . Lub atoms nyob rau hauv peb lub sij hawm muaj electrons nyob rau hauv 3 qib zog . Lub atoms nyob rau hauv plaub lub sij hawm muaj electrons nyob rau hauv 4 qib zog.

Tom qab ntawd, lo lus nug yog, koj nrhiav tau lub zog loj npaum li cas? Txhua theem pib zog tuaj yeem muaj txog li 2n2 electrons, qhov twg n yog tus naj npawb ntawm cov qib . Yog li, thawj qib tuaj yeem muaj txog li 2 electrons, 2 (12) = 2; qhov thib ob mus txog 8 electrons, 2 (22) = 8; qhov thib peb txog 18, 2 (32) = 18; thiab lwm yam.

Tsis tas li lo lus nug yog, dab tsi yog lub zog tseem ceeb hauv kev teeb tsa hluav taws xob?

Kev npaj ntawm electrons nyob rau hauv ib qho atom hu ua electronic configuration thiab cov electrons tau sau raws li cov zog ntawm qib as: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f.

Dab tsi yog qib zog hauv chemistry?

Qib zog (tseem hu ua electron shells) yog qhov kev ncua deb ntawm lub nucleus ntawm lub atom qhov twg electrons yuav pom. Electrons yog me me, tsis zoo them cov khoom nyob rau hauv ib lub atom uas txav ib ncig ntawm lub zoo nucleus ntawm qhov chaw. Qib zog me ntsis zoo li cov kauj ruam ntawm lub staircase.
