Cov Lewis Qauv rau ntsev NaCl , qhia ob ions uas muaj lawv (Tam sim no) cov plhaub sab nraud ntawm electronsfilled nrog ib qho octet tiav. Nyob rau hauv cov ntaub ntawv ntawm sodium cation, lub plhaub taum yog qhov sab nraud ntawm 'core' electron plhaub. Hauv Chloride ion, lub plhaub sab nraud ntawm valence electrons ua tiav nrog 8 electrons.

Ib yam li ntawd, koj tuaj yeem nug, lub npe ntawm cov mis NaCl yog dab tsi?

Sodium chloride

Ib yam li ntawd, qhov kev teeb tsa hluav taws xob ntawm NaCl yog dab tsi? Cov electron configurations ntawm sodium thiab chloride ions-cov khoom ntawm cov ntsev ntsev ( NaCl )-muab kev pom muaj txiaj ntsig rau txoj cai octet. Sodium (Na) nrog rau electron configuration ntawm 1s22s ib22 ib p63s ib1 swb nws sab hnub poob tshaj 3s hluav taws xob thiab, yog li ntawd, Na+ion muaj electron configuration ntawm 1s22s ib2 2 ib p6.

Ua raws li qhov xav tau, tus qauv ntawm NaCl yog dab tsi?

NaCl muaj ib tug cubic unit cell. Nws yog qhov zoo tshaj plaws kev xav ntawm lub ntsej muag-centered cubic array ntawm anions nrog interpenetratingfcc cation lattice (los yog vice-versa). Lub cell zoo li qub txawm tias koj pib nrog anions lossis cations ntawm cov ces kaum. Txhua ion yog 6-coordinate thiab muaj ib lub zos octahedral geometry.

Lub cim Lewis rau Na + yog dab tsi?

Cov dots hauv Lewis dot qauv symbolize lub atom lub ntsiab. Txij li thaum Na^+ yog ib qho zoo ion (cation) nrog rau tus nqi ntawm +1, nws qhia tau hais tias nws tau poob ib electron. Vim Na muaj ib tug electron, pib nrog, thiab tam sim no nws ploj lawm, Na^ + yuav tsis muaj dots..
