Sodium chloride (NaCl) yog ib qho piv txwv classic ntawm ib ionic compound , los yog compound tsim los ntawm ionic daim ntawv cog lus . Dej (H2O) feem ntau hu ua molecular compound, tab sis tseem hu ua covalent compound vim nws yog ib qho kev sib txuas tsim los ntawm covalent bonds.
Tsis tas li ntawd, yog NaCl yog ib qho molecule?
Lub hauv paus muaj pes tsawg leeg ntawm ib qho kev sib xyaw tuaj yeem qhia tias siv cov tshuaj formula. Qhov feem ntau piv txwv ntawm ioniccompound yog sodium chloride NaCl , zoo dua lub npe hu ua tablesalt. Tsis zoo li covalent tebchaw, tsis muaj qhov zoo li ib molecule ntawm ib qho ionic compound.
Kuj Paub, puas yog ib qho molecule ib qho sib xyaw? A molecule yog tsim thaum ob los yog ntau tshaj atoms ntawm anelement chemically koom ua ke. Yog tias hom atoms txawv ntawm ib leeg, a compound yog tsim. Tsis yog tag nrho molecules yog tshuaj sib xyaw ,vim ib molecules , xws li hydrogen gas lossis ozone, tsuas yog muaj ib lub ntsiab lus lossis hom atom.
Tom qab ntawd, lo lus nug yog, dab tsi ntawm molecule yog NaCl?
Sodium Chloride , NaCl . Cov ntaub ntawv classic ofionic bonding, lub sodium chloride molecule Cov ntaub ntawv los ntawm theionization ntawm sodium thiab chlorine atoms thiab attraction ntawm theresulting ions.
Puas yog dej yog molecule lossis ib qho sib xyaw?
Dej as a Compound thiab Molecule A compound tsim thaum twg ob los yog ntau tshaj atoms formchemical bonds nrog ib leeg. Cov tshuaj formula rau dej yog H2O, uas txhais tau tias txhua molecule ntawm dej muaj ib tug oxygen atom chemically bonded rau ob hydrogen atoms. Yog li, dej yog a compound.

Puas yog beryllium yog hlau lossis nonmetal lossis metalloid?
Beryllium yog hlau. Nws yog nyob rau hauv alkaline ntiaj teb hlau pawg nyob rau hauv lub periodic lub rooj thiab muaj tshuaj thiab lub cev muaj zog zoo ib yam li cov magnesium thiab txhuas, tab sis muaj ib tug ntau dua melting point tshaj ob qho tib si
Puas yog carbon hlau lossis nonmetal lossis metalloid?
Carbon muaj 4 electrons nyob rau hauv nws lub valence plhaub uas ua rau nws ib tug metalloid tab sis feem ntau nws yog suav hais tias yog tsis yog hlau
Puas yog malleable hlau lossis nonmetal lossis metalloid?
Hlau, Metalloids, thiab Nonmetals. Cov ntsiab lus tuaj yeem faib ua hlau, nonmetals, lossis metalloids. Cov hlau yog cov khoom siv hluav taws xob zoo ntawm cov cua sov thiab hluav taws xob, thiab tuaj yeem ua tau zoo (lawv tuaj yeem muab hammered rau hauv cov ntawv) thiab ductile (lawv tuaj yeem kos rau hauv cov hlau). Cov metalloids yog nruab nrab hauv lawv cov khoom
Puas yog chf3 polar lossis nonpolar molecule?
Yog tias koj saib ntawm Lewis qauv rau CHF3 nws tsis tshwm sim ib qho symmetrical molecule. Ib tug polar molecule tshwm sim los ntawm qhov sib npaug / unsymmetrical sib koom ntawm valence electrons. Hauv CHF3 qhov kev sib koom tsis sib npaug thiab muaj cov net dipole. Yog li ntawd, CHF3- yog ib tug polar molecule
