Sulfur muaj ib qho ntxiv hluav taws xob khub nyob rau hauv nws 3s subshell kom nws muaj peev xwm undergo excitation ib zaug ntxiv thiab tso rau hluav taws xob hauv lwm qhov khoob 3d ib orbital. Tam sim no sulfur muaj 6 unpair electrons uas txhais tau tias nws tuaj yeem tsim 6 covalent daim ntawv cog lus kom muab tag nrho ntawm 12 electrons nyob ib ncig ntawm nws lub plhaub valence.

Yog li ntawd, muaj pes tsawg 3p electrons puas sulfur?

Tam sim no, sulfide anion, S2-, yog tsim thaum ob electrons ntxiv rau qhov nruab nrab sulfur atom. Raws li koj tuaj yeem pom hauv kev teeb tsa ntawm qhov nruab nrab atom, ob qho no electrons yuav ntxiv rau lub 3 ua p -orbitals, uas tuaj yeem tuav qhov siab tshaj plaws ntawm rau electrons nruab nrab ntawm lawv.

Kuj Paub, leej faj puas muaj 10 electrons? Atoms nyob rau lub sijhawm no tuaj yeem ua raws li txoj cai octet, tab sis muaj cov xwm txheej uas lawv ua tau nthuav lawv valence shells kom haum ntau tshaj yim electrons . Cov sulfur atom hauv SF₄ muaj 10 valence electrons thiab 12 valence electrons hauv SF₆.

Tib neeg kuj nug, dab tsi yog qhov kev teeb tsa hluav taws xob rau leej faj?

[Ne] 3s² 3p4

Vim li cas 4s siab zog dua 3d?

Raws li Aufbau txoj cai, lub 4s ib sublevel tau sau ua ntej 3d ib sublevel vim 4s ib yog qis hauv zog . Raws li cov 3d ib sublevel ua populated nrog electrons, tus txheeb ze lub zog ntawm 4s ib thiab 3d ib fluctuate txheeb ze rau ib leeg thiab 4s ib xaus li siab dua hauv zog raws li cov 3d ib sublevel sau.
