Polarizability nce zuj zus ntawm kab ntawm lub sijhawm. Ib yam li ntawd, loj dua molecules feem ntau ntau polarizable dua cov me. Dej yog ib qho polar molecule, tab sis alkanes thiab lwm yam hydrophobic molecules yog ntau polarizable.
Puas yog polar molecules polarizable?
Polarisability yog hais txog qib uas electron huab nyob rau hauv ib lub moleculelossis atom tuaj yeem cuam tshuam los ntawm ib qho hluav taws xob sab nraud. Txhua yam, polar los yog tsis, muaj ib tug polarisability.
Lub ntsiab lus twg muaj qhov polarizability siab tshaj?
Ib qho piv txwv zoo feem ntau hais yog qhov sib txawv ntawm polarisability hauv halogens: Fluorine yog qhov tsawg tshaj plaws polarisable thaum iodine yog qhov polarisable tshaj plaws. Qhov no yog vim qhov sib txawv ntawm cov atom. Iodine muaj huab cua loj dua thiab ntau dua diffuse electron, tso cai rau kev yooj yim ntawm electron txav hauv huab electron.
Dab tsi cuam tshuam rau Polarizability?
Molecular orientation, atomic radii, thiab electron ntomyog peb yam tseem ceeb uas cuam tshuam rau Polarizability raws li hauv qab no: Raws li tus naj npawb ntawm electrons nce, kev tswj ntawm kev faib khoom ntawm tus nqi los ntawm nuclear nqi yuav tsawg dua, thiab yog li Polarizability ntawm atom nce.
Qhov twg yog polarizable tshaj plaws?
Antimony (Sb) yog qhov polarizable tshaj plaws vim nws cov valence electrons nyob deb tshaj plaws ntawm lub nucleus thiab tsawg kawg tuav.

Puas yog qhov tsis zoo ntawm ntau qhov ntau lossis cov lus?
Lub npe tsis zoo tuaj yeem suav tau lossis suav tsis tau. Feem ntau, feem ntau siv, cov ntsiab lus, daim ntawv ntau ntau kuj yuav yog qhov tsis zoo. Txawm li cas los xij, hauv cov ntsiab lus tshwj xeeb,ntau daim ntawv tuaj yeem ua tsis tiavpiv txwv li.
Txhais tau tias yog polarizable?
Polarizability feem ntau yog hais txog qhov nyiam ntawm qhov teeb meem, thaum raug hluav taws xob, kom tau txais hluav taws xob dipole lub sij hawm nyob rau hauv kev faib ua feem rau qhov chaw thov. Nws yog ib yam khoom ntawm txhua qhov teeb meem, ntau npaum li qhov teeb meem yog tsim los ntawm cov khoom siv hluav taws xob uas muaj hluav taws xob, uas yog protons thiab electrons.
Pob polar molecules puas muaj cohesion ntau dua?
Lub zog sib koom ua ke nruab nrab ntawm cov polar molecules muaj zog dua li ntawm cov tsis-polar molecules, xws li cov roj los yog kua qab zib. Yog vim li cas koj thiaj ua tau dej "pw" loj dua li cov roj los yog syrup. Pob polar lossis nonpolar molecules muaj adhesion ntau dua?
Covalently bonded molecules yog polar?
Ib tug polar covalent daim ntawv cog lus muaj tshwm sim thaum atoms nrog cov electronegativities sib txawv sib koom cov electrons hauv cov nyiaj sib cog lus. Xav txog hydrogen chloride (HCl) molecule. … Qhov sib faib tsis sib npaug ntawm cov khub sib txuas ua rau muaj qhov tsis zoo ib feem ntawm cov tshuaj chlorine atom thiab ib nrab nqi zoo ntawm hydrogen atom.
Vim li cas cov molecules ntawm hydrocarbons tsis yog polar?
Hydrocarbons ua tsis yog polar. Yog li, hydrocarbons yog nonpolar vim qhov tsawg dua electronegativity sib txawv ntawm carbon thiab hydrogen atoms tam sim no nyob rau hauv hydrocarbons. Polarity yog qhov txav ntawm electrons lossis ions, vim hydrocarbons tsis yog polar, hydrocarbons yog inert piv rau lwm pab pawg ua haujlwm.
