Hauv daim ntawv cog lus covalent ib khub ntawm electrons tau sib koom ntawm ob lub atoms 'txuas' los ntawm covalent daim ntawv cog lus. Yog li daim ntawv cog lus doublecovalent muaj ob khub ntawm electrons raug sib koom, yog li intotal plaub electrons.
Ib yam li ntawd, tej zaum koj yuav nug, muaj pes tsawg electrons sib koom ua ob daim ntawv cog lus?
Plaub electrons
thaum ib daim ntawv cog lus ob npaug yog tsim muaj pes tsawg electrons raug faib? Ob npaug thiab triple covalent bonds tshwm sim thaum plaub los yog rau electrons yog qhia nruab nrab ntawm twoatoms, thiab lawv tau qhia nyob rau hauv Lewis lug los ntawm kos ob orthree kab txuas ib atom mus rau lwm tus.
Nyob rau hauv no, muaj pes tsawg khub ntawm electrons sib koom nyob rau hauv ib daim ntawv cog lus?
Hauv ib ib daim ntawv cog lus ib khub ntawm electrons yog qhia ,cu ib hluav taws xob tau txais txiaj ntsig los ntawm txhua qhov ntawm cov atoms. Ob daim ntawv cog lus share ob khub ntawm electrons thiab triple daim ntawv cog lus qhia peb khub ntawm electrons . Bonds sib koom ntau tshaj ib khub ntawm electrons hu ua ntau covalent daim ntawv cog lus.
Qhov piv txwv ntawm ob daim ntawv cog lus yog dab tsi?
A ob daim ntawv cog lus yog tsim thaum ob atoms sib koom obpairs ntawm electrons. Kev sib koom ntawm ob lub electrons yog hu ua acovalent daim ntawv cog lus . Ob daim ntawv cog lus yog ua los ntawm ib tug pi daim ntawv cog lus ib sigma daim ntawv cog lus . Piv txwv ntawm compounds nrog ob daim ntawv cog lus suav nrog cov pa roj carbon dioxide, acetone, thiab ozone.

Yuav ua li cas yog daim ntawv cog lus sib txawv ntawm daim ntawv cog lus ionic?
Qhov sib txawv ntawm cov ionic thiab covalent daim ntawv cog lus yog tias covalent daim ntawv cog lus yog tsim thaum ob lub atoms sib koom electrons. Ionic bonds yog lub zog uas tuav ua ke electrostatic zog ntawm kev nyiam ntawm cov ions oppositely them. Ionic bonds muaj qhov sib txawv electronegativity ntau dua lossis sib npaug li 2
Dab tsi yog qhov txawv ntawm daim ntawv cog lus lub zog thiab daim ntawv cog lus dissociation zog?
Qhov sib txawv tseem ceeb ntawm kev sib txuas ntawm lub zog thiab lub zog bonddissociation yog tias lub zog sib txuas yog qhov nruab nrab ntawm lub zog xav tau los rhuav tshem tag nrho cov kev sib txuas ntawm tib ob hom atoms nyob rau hauv ib qho chaw sib txuas whereas daim ntawv cog lus dissociation zog yog tus nqi ntawm cov hluav taws xob xav tau los rhuav tshem ib qho kev sib koom ua ke inhomolysis
Puas yog daim ntawv cog lus hydrogen zoo ib yam li daim ntawv cog lus?
Hydrogen daim ntawv cog lus yog lub npe muab rau electrostatic kev sib cuam tshuam ntawm tus nqi zoo ntawm hydrogen atom thiab tus nqi tsis zoo ntawm oxygen atom ntawm ib qho chaw nyob sib ze. Covalent daim ntawv cog lus yog qhov sib cuam tshuam electrostatic ntawm ob lub atom hauv tib lub molecule
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
C muaj pes tsawg daim ntawv cog lus hauv co2?
2 sigma daim ntawv cog lus
