Hauv chemistry, a daim ntawv cog lus los yog tshuaj daim ntawv cog lus yog ib qho kev sib txuas ntawm cov atoms hauv cov molecules los yog cov tebchaw thiab nruab nrab ntawm ions thiab molecules hauv cov muaju. A daim ntawv cog lus sawv cev rau ib tug ntev attraction ntawm txawv atoms, molecules los yog ions.
Xav txog qhov no, dab tsi yog daim ntawv cog lus tshuaj hauv kev tshawb fawb?
Tshuaj tiv thaiv . A chemical bond yog lub cev tshwm sim ntawm tshuaj Cov khoom raug tuav ua ke los ntawm kev nyiam ntawm atoms rau ib leeg los ntawm kev sib koom, nrog rau kev sib pauv, ntawm electrons - lossis electrostatic rog.
Ib tug kuj yuav nug, dab tsi yog ob hom kev cog lus? Muaj ob lub ntsiab hom ntawm chemical daim ntawv cog lus uas tuav atoms ua ke: covalent thiab ionic / electrovalent daim ntawv cog lus . Atoms uas sib koom electrons hauv tshuaj daim ntawv cog lus muaj covalent daim ntawv cog lus . Cov pa oxygen molecule (O2) yog ib qho piv txwv zoo ntawm molecule nrog covalent daim ntawv cog lus.
Tib neeg kuj nug tias, 4 hom kev cog lus yog dab tsi?
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.
Dab tsi yog 3 hom chemical bonds?
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 qho atom ob qho tib si, thiab yog qhov tshwm sim ntawm qhov kev nyiam ntawm cov ions uas ua rau muaj kev cuam tshuam. Qhov no tshwm sim ntawm atoms nrog qhov sib txawv electronegativity feem ntau loj dua 1.8.

Dab tsi yog qhov txawv ntawm kev siv science thiab natural science?
Natural sciences cuam tshuam nrog lub ntiaj teb lub cev thiab suav nrog astronomy, biology, chemistry, geology, thiab physics. Applied science yog cov txheej txheem ntawm kev siv cov kev paub txog kev tshawb fawb rau cov teeb meem, thiab siv rau hauv kev lag luam xws li engineering, kev saib xyuas kev noj qab haus huv, kev siv technology, thiab kev kawm thaum yau
Kev sib raug zoo ntawm science thiab social science yog dab tsi?
Kev tshawb fawb (tseem hu ua ntshiab, ntuj, lossis kev tshawb fawb lub cev) thiab kev tshawb fawb txog kev sib raug zoo yog ob hom kev tshawb fawb uas cuam tshuam nrog tib cov qauv kev tshawb fawb thiab cov khoom ntawm lawv tus kheej txoj cai lij choj. Kev tshawb fawb muaj kev txhawj xeeb ntau dua nrog kev kawm xwm, thaum kev tshawb fawb txog tib neeg kev coj cwj pwm thiab kev sib raug zoo
Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog tsib lub hauv paus Circuit Court Cheebtsam lawv lub tsev yog dab tsi?
Cov no yog cov feem ntau siv: resistors. Capacitors. LEDs. Transistors. Inductors. Integrated Circuits
Hydrogen bonds yog dab tsi thiab lawv tseem ceeb hauv lub cev li cas?
Hydrogen bonding yog qhov tseem ceeb hauv ntau cov txheej txheem tshuaj. Hydrogen bonding yog lub luag haujlwm rau dej cov kuab tshuaj tshwj xeeb. Hydrogen bonds tuav cov kab sib txuas ntawm DNA ua ke, thiab lawv yog lub luag haujlwm rau kev txiav txim siab peb-dimensional qauv ntawm folded proteins nrog rau cov enzymes thiab cov tshuaj tiv thaiv
