Dej yog polar molecule

A dej molecule yog tsim thaum ob atoms ntawm hydrogen daim ntawv cog lus covalently nrog ib tug atom ntawm oxygen. Nyob rau hauv covalent bond electrons yog sib koom ntawm atoms. Hauv dej kev sib koom tsis sib npaug.

Raws li txoj cai, cov dej molecules sib txuas ua ke li cas?

Lub me ntsis zoo them hydrogen atoms ces attracted rau me ntsis tsis zoo nqi oxygen atoms ntawm lwm yam dej molecules . Cov zog ntawm kev nyiam no yog hu ua hydrogen bonds.

Tsis tas li ntawd, 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.

Tib neeg kuj nug, ua li cas dej molecule?

A dej molecule muaj peb atoms; ib qho oxygen atom thiab ob lub hydrogen atoms, uas yog kev sib txuas ua ke zoo li cov hlau nplaum me me. Cov atoms muaj cov teeb meem uas muaj cov nucleus nyob hauv nruab nrab. Qhov kev nyiam ntawm cov protons thiab electrons yog qhov ua kom lub atom ua ke.

Dab tsi ntawm daim ntawv cog lus yog dej?

Dej yog ib tug polar molecule A dej molecule yog tsim thaum ob atoms ntawm hydrogen daim ntawv cog lus covalently nrog ib tug atom ntawm oxygen. Hauv covalent daim ntawv cog lus electrons sib koom ntawm atoms. Hauv dej kev sib koom tsis sib npaug. Cov pa oxygen atom nyiam cov electrons ntau dua li cov hydrogen.
