Key Takeaway. Kev tsim cov ntawv cog lus qis dua tag nrho lub zog ntawm lub cev, lub zog yuav tsum tau ua kom sib cais cov atoms lossis ions, thiab muaj qhov kev pom zoo nyob deb.
Lub hom phiaj ntawm kev tsim tshuaj lom neeg yog dab tsi?
Tshuaj tiv thaiv tuav cov molecules ua ke thiab tsim kev sib txuas ib ntus uas tseem ceeb rau lub neej. Hom tshuaj tiv thaiv xws li covalent, ionic, thiab hydrogen bonds thiab London dispersion rog.
Kev tsim cov tshuaj lom neeg muaj feem cuam tshuam li cas?
Tshuaj tiv thaiv yog lub zog ntawm kev nyiam uas khi atoms ua ke. Bonds yog tsim thaum valence electrons, cov electrons nyob rau sab nraud hluav taws xob "plhaub" ntawm ib lub atom, sib cuam tshuam. … Yog li ntawd, cov electrons zoo li yuav pom nyob ze ntawm ib qho atom feem ntau ntawm lub sijhawm.
Yuav ua li cas rau atoms thaum lawv tsim tshuaj tiv thaiv?
Atoms tsim cov tshuaj tiv thaiv rau ua kom lawv cov khoom siv hluav taws xob sab nraud ruaj khov. … Ib daim ntawv cog lus ionic, qhov twg ib lub atom tseem ceeb pub ib lub tshuab hluav taws xob rau lwm tus, tsim thaum ib lub atom ruaj khov los ntawm kev poob nws cov electrons sab nraud thiab lwm cov atoms ruaj khov (feem ntau yog los ntawm kev sau nws lub plhaub valence) los ntawm kev txais cov electrons.
Qhov twg ntawm cov hauv qab no cuam tshuam rau qhov loj ntawm lub lattice zog rau ib qho ionic compound xaiv txhua yam uas siv?
Ob yam tseem ceeb uas ua rau muaj qhov loj ntawm lub lattice zogyog tus nqi thiab lub vojvoog ntawm cov ions sib txuas.
