Hauv H2O molec, ob dej Cov molecules yog sib txuas los ntawm Hydrogen daim ntawv cog lus tab sis cov daim ntawv cog lus ntawm ob H - O daim ntawv cog lus hauv ib dej molecule yog covalent.

Hauv qhov no, hom ntawv cog lus twg pom nyob hauv dej?

Dej muaj polar covalent bonds nruab nrab ntawm nws cov atoms, thiab feem ntau tsim hydrogen bonds nrog rau lwm cov polar molecules, nrog rau lwm cov dej molecules.

yog h2o yog covalent lossis ionic daim ntawv cog lus? Piv txwv li, dej ( H2O ) yog a compound muaj ob lub hydrogen atoms sib txuas rau ib qho oxygen atom. Cov atoms hauv ib compound tuaj yeem tuav ua ke los ntawm ntau yam kev sib cuam tshuam, xws li los ntawm covalent bonds rau electrostatic zog hauv ionic daim ntawv cog lus . Piv txwv li H2O yog tuav ua ke los ntawm polar covalent bonds.

Ua li no, vim li cas h2o yog daim ntawv cog lus?

Hauv kev xaus, dej muaj ib tug covalent bond vim hais tias ntawm cov pa oxygen thiab hydrogen - lawv sib koom electrons kom muaj kev ruaj ntseg, thiab lawv cov electronegativities nyob ze txaus rau lawv. daim ntawv cog lus xav txog covalent.

Dab tsi yog 4 hom kev sib cog lus hauv chemistry?

4 Hom Tshuaj Bonds

  • 1 Ionic daim ntawv cog lus. Ionic bonding cuam tshuam nrog kev hloov ntawm ib qho hluav taws xob, yog li ib lub atom tau txais ib qho hluav taws xob thaum ib lub atom poob ib qho hluav taws xob.
  • 2 Covalent bond. Kev sib cog lus ntau tshaj plaws hauv cov organic molecules, covalent daim ntawv cog lus koom nrog kev sib koom ntawm electrons ntawm ob lub atoms.
  • 3 Polar daim ntawv cog lus.
