Carbon (C), raws li pawg 14 lub caij, muaj plaub lub electrons hauv nws lub plhaub sab nrauv. Cov pa roj carbon feem ntau faib cov hluav taws xob kom ua tiav lub plhaub valence, tsim cov ntawv cog lus nrog ntau lwm cov atoms.
Atom puas tuaj yeem poob 4 electrons?
Teb: Yog tias lub caij muaj 4 electrons nyob rau hauv nws lub plhaub sab nraud, ces nws yuav yog 4 poob electrons lossis nce electrons los ua lub plhaub sab nraud octet. Piv txwv li: Tus naj npawb atomic ntawm silicon yog 14.
Lub sijhawm twg muaj 4 lub plhaub hluav taws xob?
P-thaiv cov ntsiab lus ntawm sijhawm 4 muaj lawv lub plhaub valence tsim los ntawm 4s thiab 4p subshells ntawm plaub (n=4) plhaub thiab ua raws li txoj cai octet.
Ua atoms nrog 4 valence electrons nce lossis poob electrons?
Pab IV A atoms muaj plaub lub valence electrons kom ruaj khov cov atoms poob plaub los yog tau plaub electrons kom ua tiav. Poob 2 electrons tuaj yeem tsim tau lub subshell puv.
Vim li cas 3rd plhaub 8 lossis 18?
Txhua lub plhaub tuaj yeem muaj tus lej tas li ntawm cov hluav taws xob, txog li ob lub tshuab hluav taws xob tuaj yeem tuav thawj lub plhaub, txog li yim (2 + 6) electrons tuaj yeem tuav lub plhaub thib ob, txog li 18 (2 + 6 + 10).) tuaj yeem tuav lub plhaub thib peb thiab lwm yam. …
