Molecular geometry yog qhov kev npaj peb-dimensional ntawm cov atoms uas yog a molecule . Nws suav nrog cov general puab ntawm molecule nrog rau qhov ntev ntawm daim ntawv cog lus, daim ntawv cog lus, lub kaum sab xis thiab lwm yam geometrical tsis uas txiav txim siab txoj haujlwm ntawm txhua lub atom.
Kuj paub yog, dab tsi yog qhov zoo li hauv chemistry?
Molecules muaj cov duab . Muaj ntau yam pov thawj ntawm kev sim rau qhov tshwm sim-los ntawm lawv lub cev rau lawv tshuaj reactivity. Me me molecules-molecules nrog ib lub hauv paus atom-muaj cov duab uas tuaj yeem kwv yees tau yooj yim. Qhov no puab yog hu ua bent los yog angular.
Tsis tas li ntawd, vim li cas cov duab molecular tseem ceeb hauv chemistry? A molecule muaj tus yam ntxwv loj thiab puab . Qhov tseeb puab ntawm a molecule feem ntau yog heev tseem ceeb rau nws txoj haujlwm hauv lub cell muaj sia. Molecular puab Nws yog ib qho tseem ceeb hauv biology vim nws txiav txim siab li cas biological molecules lees paub thiab teb rau ib leeg nrog qhov tshwj xeeb.
Ib yam li ntawd, koj tuaj yeem nug, cov duab ntawm cov molecules yog dab tsi?
Lub tsib zoo tagnrho cov duab yog: linear, trigonal planar, tetrahedral, trigonal bypramidal thiab octahedral. Ib qho tseem ceeb uas yuav tsum nco ntsoov txog molecular zoo yog tias tag nrho cov diatomic (sib xyaw nrog ob lub atoms) cov kab sib txuas.
Koj pom cov duab molecular li cas?
Cov kauj ruam siv los nrhiav cov duab ntawm cov molecule
- Kos tus qauv Lewis.
- Suav tus naj npawb ntawm cov pab pawg electron thiab txheeb xyuas lawv raws li daim ntawv cog lus ntawm pawg hluav taws xob lossis ib leeg ntawm cov hluav taws xob.
- Lub npe electron-group geometry.
- Saib ntawm txoj hauj lwm ntawm lwm cov atomic nuclei nyob ib ncig ntawm lub hauv paus txiav txim siab cov molecular geometry.

Dab tsi yog qhov txawv ntawm cov chemistry thiab organic chemistry?
Organic chemistry yog suav tias yog ib qho kev qhia ntawm chemistry. Thaum lub sij hawm lub kaus dav dav 'chemistry' yog kev txhawj xeeb nrog kev sib xyaw thiab kev hloov pauv ntawm txhua yam teeb meem, cov khoom siv tshuaj lom neeg tsuas yog txwv rau kev kawm ntawm cov organic tebchaw xwb
Dab tsi yog siv lub puab tsaig sab sauv hauv vernier caliper?
Lub puab tsaig sab saud yog qhov me me, nkhaus sab hauv, thiab yog siv los ntsuas qhov ntev ntawm cov khoom hollow xws li lub tog raj kheej thiab lwm yam. Ib qho vernier calipers uas tseem hu ua Slide Calipers
Dab tsi yog qhov zoo ntawm folded puab membrane hauv mitochondria?
Kev ua haujlwm ntawm folds hauv mitochondria yog ua kom thaj chaw saum npoo. Qhov no sab hauv folded ib feem ntawm mitochondria (lub puab daim nyias nyias) yog lub luag hauj lwm rau cell respiration (tus txheej txheem ntawm zom cov carbohydrates (qab zib) kom lub zog)
Tus qauv qauv yog dab tsi Qhov txawv ntawm tus qauv qauv thiab tus qauv molecular yog dab tsi?
Cov mis mos molecular siv cov cim tshuaj thiab cov ntawv sau npe los qhia cov naj npawb ntawm cov atoms sib txawv hauv cov molecule lossis compound. Ib qho empirical formula muab qhov yooj yim tshaj plaws, tag nrho tus lej piv ntawm atoms hauv ib qho chaw. Cov qauv qauv qhia txog kev sib koom ua ke ntawm cov atoms hauv cov molecule
Lub puab tsaig ntawm lub puab tsaig yog dab tsi?
Lub puab tsaig ntawm lub puab tsaig yog dab tsi thiab koj tuaj yeem pom cov duab ntawm lub puab tsaig ntawm lub puab tsaig? Cov no feem ntau tsis sib xws thiab yog ib txwm tiaj tus. Cov cell yog tsim los ntawm ntau qhov chaw nrog rau ib daim nyias nyias nyias nyob rau sab nraud ntawm tes. Cov no tuaj yeem pom tau yooj yim nyob rau hauv microscope
