Muaj peb yam loj hom chemical bonds : ionic, covalent , thiab metallic. Ionic daim ntawv cog lus daim ntawv vim kev hloov ntawm ib hluav taws xob los ntawm ib atom lwm tus. Covalent bonds koom nrog kev sib koom ntawm electrons ntawm ob atoms.
Ua kom pom qhov no, 3 hom kev sib cog lus tshuaj yog dab tsi?
Muaj peb lub ntsiab hom ntawm daim ntawv cog lus : ionic, covalent thiab metallic. Cov no daim ntawv cog lus tshwm sim thaum electrons raug xa mus los ntawm ib tug atom ob lwm, thiab yog ib tug tshwm sim ntawm attraction ntawm lub resulting oppositelycharged ions. Qhov no tshwm sim ntawm atoms nrog ib qho electronegativitydifference feem ntau loj dua 1.8.
Tsis tas li ntawd, chemical bond yog dab tsi thiab nws hom? Chemical bonds yog lub zog uas tuav atomstogether 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 electronegativitytransfer electrons los ua ions. Cov ions ces yog attracted rau ib leeg. Qhov kev nyiam no hu ua ionic daim ntawv cog lus.
Tsis tas li ntawd, 4 hom kev sib cog lus yog dab tsi?
4 Hom Tshuaj Bonds
- 1 Ionic daim ntawv cog lus. Ionic bonding muaj 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 anelectron.
- 2 Covalent bond. Kev sib cog lus ntau tshaj plaws hauv cov organic molecules, acovalent daim ntawv cog lus koom nrog kev sib koom ntawm electrons ntawm obatoms.
- 3 Polar daim ntawv cog lus.
Dab tsi yog 4 hom kev sib cog lus carbon tuaj yeem tsim tau?
Peb qhov loj hom ntawm covalent daim ntawv cog lus yog ib leeg, ob, thiab triple daim ntawv cog lus . A carbon atom tuaj yeem tsim cov hauv qab no daim ntawv cog lus : Plaub ib leeg daim ntawv cog lus . Ib leeg thiab ob leeg daim ntawv cog lus.

Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi yog qhov sib txawv chemical bonds?
Chemical bonds yog lub zog uas tuav cov atoms ua ke los ua cov tebchaw lossis molecules. Cov khoom siv tshuaj muaj xws li covalent, polar covalent, thiab ionic bonds. 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 yog hu ua ionic bond
Dab tsi yog txheej txheem ntuj tsim ua rau ib hom pob zeb hloov mus rau lwm hom?
Peb hom pob zeb tseem ceeb yog igneous, metamorphic thiab sedimentary. Peb txheej txheem uas hloov ib lub pob zeb mus rau lwm qhov yog crystallization, metamorphism, thiab yaig thiab sedimentation. Txhua lub pob zeb tuaj yeem hloov mus rau lwm lub pob zeb los ntawm kev dhau los ntawm ib lossis ntau dua ntawm cov txheej txheem no. Qhov no tsim lub voj voog pob zeb
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
Dab tsi yog qhov txawv ntawm N hom semiconductor thiab P hom semiconductor?
Hauv N-hom semiconductor, cov khoom siv hluav taws xob feem ntau yog cov neeg nqa khoom thiab qhov yog cov neeg nqa khoom tsawg. Hauv P-hom semiconductor, qhov yog feem ntau cov neeg nqa khoom thiab cov khoom siv hluav taws xob yog cov neeg tsawg. Nws muaj qhov loj dua electron concentration thiab tsawg lub qhov concentration. Nws muaj qhov loj dua qhov concentration thiab tsawg dua electron concentration
