Cov txawv nruab nrab ib ionic thiab a covalent bond yog a covalent bond yog tsim thaum ob atoms sib koom electrons. Ionic daim ntawv cog lus yog cov rog uas tuav ua ke electrostatic rog ntawm kev nyiam ntawm qhov sib txawv ions . Ionic daim ntawv cog lus muaj electronegativity txawv ntau dua los yog sib npaug 2.
Ib yam li ntawd, yuav ua li cas yog daim ntawv cog lus sib txawv ntawm daim ntawv cog lus ionic?
Ib ionic daim ntawv cog lus yog tsim los ntawm ib tug hlau thiab tsis yog hlau. Covalent bonding yog ib hom tshuaj kev sib raug zoo nruab nrab ntawm ob lub atoms uas tsis yog xim hlau uas yog tus cwj pwm los ntawm kev sib koom ntawm khub ntawm electrons ntawm atoms thiab lwm yam covalent bonds.
Qhov thib ob, ionic bond thiab covalent bond yog dab tsi? Tshuaj Bonding Ob qhov xwm txheej hnyav ntawm chemical daim ntawv cog lus yog: Covalent daim ntawv cog lus : daim ntawv cog lus nyob rau hauv uas ib los yog ntau khub ntawm electrons tau muab faib los ntawm ob atoms. Ionic daim ntawv cog lus : daim ntawv cog lus nyob rau hauv uas ib los yog ntau dua electrons los ntawm ib lub atom raug tshem tawm thiab txuas mus rau lwm lub atom, ua rau qhov zoo thiab tsis zoo ions uas nyiam ib leeg.
Qhov thib ob, dab tsi yog daim ntawv cog lus cog lus ionic daim ntawv cog lus?
Ionic daim ntawv cog lus . daim ntawv ions , nce los yog poob lub plhaub sab nraud electrons, sau lub plhaub hluav taws xob sab nraud. Covalent bonds . daim ntawv molecules, sib koom lub plhaub sab nraud electrons, sau sab nrauv electron plhaub.
Ib co piv txwv ntawm ionic bonds yog dab tsi?
Ionic daim ntawv cog lus piv txwv muaj xws li:
- LiF - Lithium Fluoride.
- LiCl - Lithium Chloride.
- LiBr - Lithium Bromide.
- Li-Iodide Lithium Iodide.
- NaF - Sodium Fluoride.
- NaCl - Sodium Chloride.
- NaBr - Sodium Bromide.
- NaI - Sodium Iodide.

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
Dab tsi yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
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
Dab tsi yog qhov sib txawv ntawm qhov sib txawv ntawm cov kab sib txuas thiab ntau qhov sib piv?
6. (2 lub cim) Qhov sib txawv ntawm cov kab sib txuas (kev sib piv) thiab ntau qhov sib piv yog dab tsi? Cov kab sib xyaw ua ke yog npaj sib piv; uas yog, tshwj xeeb txhais tau tias yog ua ke nyob rau hauv ntau txoj kev thiab contrasted nrog rau lwm yam kev sib txuas ntawm txhais tau tias
Dab tsi yog qhov sib txawv ntawm cov kab lus sib npaug thiab qhov sib npaug sib npaug?
Cov kab lus sib npaug muaj qhov muaj txiaj ntsig zoo ib yam tab sis tau nthuav tawm nyob rau hauv ib hom ntawv sib txawv uas siv cov khoom ntawm cov lej xws li ax + bx = (a + b) x yog cov kab lus sib npaug. nruj me ntsis, lawv tsis yog 'sib npaug', yog li peb yuav tsum siv 3 kab sib luag hauv 'sib npaug' es tsis yog 2 raws li qhia ntawm no
