A chemical bond yog ib tug ntev attraction ntawm atoms, ions los yog molecules uas enables tsim ntawm tshuaj tshuaj sib xyaw. Cov daim ntawv cog lus Tej zaum yuav tshwm sim los ntawm electrostatic quab yuam ntawm attraction ntawm oppositely them ions raws li nyob rau hauv ionic daim ntawv cog lus los yog los ntawm kev sib koom ntawm electrons li hauv covalent bonds.

Xav txog qhov no, dab tsi yog daim ntawv cog lus tiag?

Covalent tshuaj, feem ntau, muaj nyob rau hauv discrete molecules nyob rau hauv uas lub constituent atoms tshwm sim ua ke los ntawm ib tug los yog ntau yam sib txawv ib-rau-ib qho kev sib tshuam los ntawm kev sib koom ntawm electrons. Covalent daim ntawv cog lus feem ntau piav raws li qhov muaj tseeb tshuaj daim ntawv cog lus.

Tsis tas li ntawd, dab tsi yog daim ntawv cog lus tshuaj hauv kev tshawb fawb? Tshuaj tiv thaiv . A chemical bond yog lub cev tshwm sim ntawm tshuaj Cov khoom raug tuav ua ke los ntawm kev nyiam ntawm atoms rau ib leeg los ntawm kev sib koom, nrog rau kev sib pauv, ntawm electrons - lossis electrostatic rog.

Cov lus nug tseem yog, puas yog daim ntawv cog lus hydrogen yog ib daim ntawv cog lus tiag tiag?

A hydrogen daim ntawv cog lus yog lub electromagnetic attraction tsim ntawm ib feem zoo them hydrogen atom txuas rau lub atom heev electronegative thiab lwm tus nyob ze electronegative atom. A hydrogen daim ntawv cog lus yog ib hom kev sib tshuam dipole-dipole; nws tsis yog ib tseeb chemical bond.

Dab tsi yog chemical bond nrog piv txwv?

Piv txwv ntawm Chemical Bonds : 1. Ib leeg covalent bonds daim ntawv thaum tsuas yog ib khub ntawm electrons sib koom ntawm atoms. Qhov no feem ntau nrog cov ntsiab lus uas tsis yog xim hlau. Dej yog H2O, txhais tau hais tias nws muaj ib qho oxygen atom txuas rau ob lub hydrogen atoms thiab txhua daim ntawv cog lus yog ib leeg covalent bond.
