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..

Lewis qauv rau c3h4 yog dab tsi?
Txhua daim duab Lewis dot siv 16 valence electrons thiab sau lub plhaub sab nraud ntawm txhua lub atom. Txawm li cas los xij, cov atoms yuav raug teeb tsa thiab sib txuas sib txawv. Rau cov qauv C3H4 Lewis, suav tag nrho cov valence electrons rau C3H4 molecule (C3H4 muaj 16 valence electrons)
Dab tsi yog lwm lo lus rau cov qauv qauv?
Standard form yog lwm lub npe forscientific notation, i.e. 876 = 8.76 x 102. standardform yog txoj kev niaj zaus ntawm kev sau cov lej hauv cov lej lej, piv txwv li
Tus qauv ntsuas kub thiab siab yog dab tsi Vim li cas tus qauv tsim nyog?
Cov txheej txheem siv cov txheej txheem yog qhov tseem ceeb rau kev qhia txog cov kua dej ntws thiab qhov ntim ntawm cov kua thiab cov pa roj, uas yog nyob ntawm qhov kub thiab txias. STP feem ntau yog siv thaum cov txheej txheem hauv xeev raug siv rau kev suav
Lewis dot qauv rau XeF4 yog dab tsi?
Yees duab: Kos tus qauv Lewis rau XeF4 Thaum peb paub tias muaj pes tsawg valence electrons muaj nyob rau hauv XeF4 peb tuaj yeem faib lawv nyob ib ncig ntawm lub hauv paus atom thiab sim sau cov plhaub sab nraud ntawm txhua lub atom. Tus qauv Lewis rau XeF4 muaj tag nrho ntawm 36 valence electrons
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
