Chemical bonds yog lub zog uas tuav atoms ua ke los ua cov tebchaw lossis molecules. Chemical bonds suav nrog covalent , polar covalent , thiab ionic daim ntawv cog lus . Atoms nrog qhov sib txawv loj hauv electronegativity hloov electrons los ua ions. Tom qab ntawd cov ions yog attracted rau ib leeg. Qhov kev nyiam no hu ua ionic daim ntawv cog lus.
Tsuas yog li ntawd, 3 hom chemical bonds yog dab tsi?
Muaj peb yam tseem ceeb ntawm daim ntawv cog lus: ionic , covalent thiab hlau. Cov ntawv cog lus no tshwm sim thaum cov hluav taws xob hloov pauv los ntawm ib lub atom ob qho tib si, thiab yog qhov tshwm sim ntawm qhov kev nyiam ntawm qhov tshwm sim tawm tsam ions. Qhov no tshwm sim ntawm atoms nrog qhov sib txawv electronegativity feem ntau loj dua 1.8.
Tom qab ntawd, lo lus nug yog, qhov twg yog daim ntawv cog lus muaj zog tshaj plaws hauv chemistry? ionic daim ntawv cog lus
Tom qab ntawd, ib tug kuj yuav nug, 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.
Puas yog dej yog covalent daim ntawv cog lus?
H2O os dej Raws li nws yog feem ntau hu ua yog ib tug molecule uas muaj 2 Hydrogen molecules bonded rau ib Oxygen molecule. Raws li cov lus qhia tau hais tias qhov no ua rau H2O molecule nrog lub polar covalent bond . Zoo, electronegativity yog qhov ntsuas ntawm qhov kev nyiam daim ntawv cog lus nrhiav electrons yog rau lub caij.

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
Qhov sib txawv ntawm qhov sib txawv ntawm 97 yog dab tsi?
Teb thiab piav qhia: 9/7 x lub reciprocal = 1. 1 / 9/7 = reciprocal
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 qhov sib txawv ntawm - 12?
Qhov ntxeev ntawm 12 yog 12, lossis credit ntawm $ 12
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
