Sodium iodide (cov tshuaj formula NaI ) yog ib ionic compound tsim los ntawm cov tshuaj tiv thaiv ntawm sodium hlau thiab iodine. Raws li cov txheej txheem, nws yog cov khoom dawb, dej-soluble uas muaj 1: 1 sib xyaw ntawm sodium cations (Na.+) thiab iodide anions (I−) nyob rau hauv crystal lattice.
Tsis tas li ntawd, NaI puas muaj cov ntawv cog lus?
Hauv ionic tshuaj sib xyaw , cov atom yog tam sim no raws li ions; uas yog , raws li nqi particle. Piv txwv li, hauv NaI , cov sodium yog tam sim no raws li sodium ions thiab iodine li iodide ions. Hauv covalent compounds nyob ntawd yog tsis them ions; cov atom yog tuav ua ke los ntawm covalent bonds.
Ib sab saum toj no, puas yog pcl3 covalent lossis ionic? Hauv CCl4, atoms chlorine thiab carbon sib koom ua ke electron ua ib qho covalent daim ntawv cog lus. Ionic Cov ntawv cog lus yog tsim los ntawm electrostatic kev sib cuam tshuam ntawm ib qho electropositive thiab electronegative atom.
Kuj paub yog, yog KF ionic lossis covalent?
Tsuas yog homonuclear bonds tiag tiag covalent , thiab yuav luag zoo tag nrho ionic Cov ntawv cog lus tuaj yeem tsim ntawm pawg I thiab pawg VII cov ntsiab lus, piv txwv li, KF . Feem ntau, txawm li cas los xij, daim ntawv cog lus yog ib feem covalent thiab ib nrab ionic , txhais tau hais tias muaj ib nrab hloov ntawm electrons ntawm atoms thiab ib feem sib koom ntawm electrons.
Dab tsi yog ntau ionic NaCl lossis NaI?
NaCl yog ntau ionic vim chlorine ntau electronegative tshaj iodine. Electron nce enthalpy ntawm chlorine yog feem ntau negative ces nws muaj ntau nyiam nce electron. Ntxiv mus, electronegativity sib txawv hauv NaI yog 0.6 uas txhais tau tias nws yog ntau covalent thiab in NaCl nws yog 2.1 uas txhais tau tias nws yog ntau ionic.

Koj tuaj yeem sim ua li cas thiaj txiav txim siab seb qhov sib xyaw puas yog ionic lossis covalent?
Muaj ob peb txoj hauv kev los txiav txim siab seb daim ntawv cog lus yog ionic lossis covalent. Los ntawm kev txhais, daim ntawv cog lus ionic yog nruab nrab ntawm cov hlau thiab cov hlau tsis muaj hlau, thiab covalent daim ntawv cog lus yog nruab nrab ntawm 2 nonmetals. Yog li koj feem ntau tsuas yog saib ntawm lub rooj zaum thiab txiav txim siab seb koj cov khoom puas yog ua los ntawm cov hlau / nonmetal lossis tsuas yog 2 nonmetals xwb
