Qhov twg ntawm cov tshuaj lom neeg hauv qab no tau piav qhia los ntawm Kossel thiab Lewis? Nqe lus piav qhia: Ob qho Ionic thiab Covalent daim ntawv cog lustshwm sim los ntawm kev nyiam ntawm atoms kom muaj kev ruaj ntseg ntawm electrons. … Piav qhia: Ionic daim ntawv cog lus tau los ntawm Poob, Hloov thiab tau txais ntawm electrons.
Dab tsi yog daim ntawv cog lus tshuaj piav qhia nws nrog kev siv kossel Lewis txoj hauv kev?
Teb: Lub zog txaus nyiam uas tuav ntau yam khoom siv (atoms, ions thiab lwm yam) ua ke hauv ntau hom tshuaj hu ua chemical bond. Raws li Kossel-Lewis txoj hauv kev, kev sib cog lus tshuaj yog tsim los ntawm ob lub atom los ntawm kev hloov ntawm electrons lossis los ntawm kev sib koom ntawm electrons
Yuav ua li cas cov tebchaw yog tsim los ntawm kossel txoj hauv kev rau kev sib txuas tshuaj?
Kossel's postulates muab lub hauv paus rau cov tswv yim niaj hnub ntawm kev hloov hluav taws xob ntawm cov atoms uas ua rau ionic lossis electrovalent bondingNaCl yog electrovalent lossis ionic compound ua los ntawm sodium ions thiab chloride cov ions. Kev sib txuas hauv NaCl yog hu ua electrovalent lossis ionic bonding.
Lewis txoj kev xav ntawm tshuaj lom neeg yog dab tsi?
Lewis 'Theory of Chemical Bonding. Covalent Bonds. Lewis lub tswv yim zoo thib ob yog qhov no: ob lub atoms nyiam ib leeg (tsim ib daim ntawv cog lus) los ntawm kev sib koom ib khub ntawm electronsLewis tau thov tias cov hluav taws xob sib koom ua ib feem ntawm txhua lub atom lub teeb tsa hluav taws xob, yog li Kev sib koom ua tau zoo txhawb nqa txhua lub atom tus lej electron.
Vim li cas atoms ua ke kossel Lewis mus rau kev sib txuas tshuaj?
Ib daim ntawv cog lus tshuaj yuav txhais tau tias yog lub zog txaus nyiam lossis lub zog khi uas tuav cov atoms, ions thiab molecules ua ke. Vim li cas atom ua ke (Kossel-Lewis mus kom ze)? Qhov no qhia tau hais tias tias muaj 8 electrons (txoj cai ntawm octet) nyob rau sab nraud yuav tsum muaj feem cuam tshuam rau kev ruaj ntseg ntawm lub atom. …
