Ntau cov atoms nonmetal, suav nrog cov sulfur, zoo li tsim cov anions, uas txhais tau tias lawv gain, tsis plam electrons, kom puv nws octet.
Puas leej faj xav kom nce lossis poob electrons?
Sulfur yuav xav tau nce 2 electrons txhawm rau ua tiav qhov kev teeb tsa octet. Tsis zoo li hauv cov piv txwv calcium uas tau nthuav tawm hauv ntu dhau los, tau txais cov khoom siv hluav taws xob no yog ua tau, vim tias ua li ntawd yuav tsis pub tshaj qhov nce siab tshaj plaws ntawm peb lub electrons.
Puas muaj pes tsawg electrons nce sulfur?
Lub plhaub valence (3s thiab 3p sublevels) muaj rau lub tshuab hluav taws xob, tab sis nws xav tau yim kom ruaj khov. Xav txog txoj cai octet. Yog li ntawd, ib tug sulfur atom yuav nce ob electrons los tsim cov sulfide anion nrog tus nqi ntawm 2−, nrog rau lub cim S2−.
Tus nqi rau leej faj yog dab tsi?
Sulfur yog nyob rau hauv pawg 6 ntawm lub sij hawm. Tus nqi ntawm nws cov ions yog dab tsi, thiab tus nqi zoo lossis tsis zoo? Tus nqi yog qhov tsis zoo, txij li cov sulfur yog cov hlau tsis muaj hlau. Tus nqi ntawm cov ion yog (8 - 6)=2.
Dab tsi poob lossis nce electrons?
Cov ntsiab lus uas yog metals zoo li plam electrons thiab dhau los ua cov ions zoo hu ua cations. Cov ntsiab lus uas tsis yog hlau zoo li tau txais cov khoom siv hluav taws xob thiab ua tsis zoo ions hu ua anions. Cov hlau uas nyob rau hauv kem 1A ntawm lub sij hawm lub sij hawm tsim ions los ntawm poob ib electron.
