Peb paub tias cov qauv qauv yog qhov uas cov hlau atoms thiab tag nrho nws cov ligands nyob rau hauv ib lub dav hlauCia peb xub pom cov qauv ntawm tag nrho cov molecules muab thiab tom qab ntawd peb tuaj yeem ua tau yooj yim nrhiav peb cov lus teb. Txoj hauv kev yooj yim tshaj plaws los nrhiav cov geometry lossis cov duab ntawm cov molecule yog pom nws cov hybridisation. A yog tus nqi ntawm anion.
Qhov twg hauv qab no muaj cov qauv qauv?
Teb: xeF4 muaj cov qauv txheej txheem.. nws yog square planar nrog plaub lub hmoov nplej ntawm plaub lub ces kaum thiab ob leeg ib khub ntawm electron saum toj thiab hauv qab ntawm lub dav hlau.
Qhov twg yog qhov kev npaj?
Planar compound yog compound uas txhua lub atoms tam sim no nyob rau hauv lub compound pw nyob rau hauv tib lub dav hlau- Cia peb noj cov organic compound. Nyob rau hauv cov organic compound, cov carbon atoms yuav pw nyob rau hauv tib lub dav hlau, ces xws li compound hu ua lub planar compound. Piv txwv li, ib qho tshuaj tsw qab.
Cov molecule twg muaj cov duab plaub square?
Ib qho piv txwv ntawm ib lub square planar molecule yog xenon tetrafluoride (XeF 4) Cov molecule no yog tsim los ntawm rau qhov sib npaug sib npaug sp 3d2 (los yog d2sp3) hybrid orbitals teem ntawm 90 ° kaum. Cov duab ntawm lub orbitals yog octahedral. Ob lub orbitals muaj ib khub ntawm electrons nyob rau sab nraud ntawm lub hauv paus atom.
Lub complex twg muaj square planer qauv?
Cov kev sib koom ua ke feem ntau yog polyhedra yog octahedral, square planar thiab tetrahedral. Piv txwv li, [Co(NH3)63+yog octahedral, [Ni(Co)4] yog tetrahedral thiab [PtCl 4 2– is square planar.

Cov qauv twg hauv qab no muaj cov otoliths?
Endolymphatic infillings xws li otoliths yog cov qauv hauv lub saccule thiab utricle ntawm lub pob ntseg sab hauv, tshwj xeeb tshaj yog nyob rau hauv lub vestibular labyrinth ntawm tag nrho cov vertebrates (ntses, amphibians, tsiaj reptiles, tsiaj nyeg thiab noog.
Cov qauv thiab cov qauv rau cov kws qhia ntawv yog dab tsi?
Cov Qauv thiab Cov Qauv rau Cov Kws Qhia Ntawv (NSE) siv ib qho txiaj ntsig raws li txoj hauv kev rau cov kws qhia ntawvthiab muab cov lus piav qhia ntxaws txog qhov uas tus kws qhia ntawv muaj peev xwm ua tau. Qhov tseem ceeb ntawm txoj cai yog kev ua tau zoo hauv cov tsev kawm ntawv, chav kawm, kev tswj hwm thiab kev txhawb nqa ntawm lub tsev kawm ntawv .
Cov qauv twg muaj qhov kev daws teeb meem siab tshaj plaws?
Spatial daws teeb meem Qhov kev daws teeb meem ntawm CTyog qhov zoo tshaj qhov kev daws teeb meem ntawm magnetic resonance imaging (MRI), uas feem ntau yog 1-2 hli rau feem ntau cov kab ke thiab ntau tshaj qhov tsim nyog rau feem ntau. Kev siv tshuaj kho mob ntawm CT .
Thaum twg thiab qhov twg siv cov ntawv sau npe thaum sau cov qauv tshuaj?
Ib qho tshuaj formula yog ib qho kev qhia uas qhia cov ntsiab lus hauv ib qho kev sib txuas thiab cov txheeb ze ntawm cov ntsiab lus. Yog tias tsuas yog ib qho atom ntawm ib hom tshwj xeeb yog tam sim no, tsis muaj subscript siv. Rau atoms uas muaj ob lossis ntau dua ntawm ib hom tshwj xeeb ntawm atom tam sim no, ib daim ntawv sau npe sau tom qab lub cim rau lub atom Dab tsi yog cov ntawv sau npe siv rau hauv cov qauv tshuaj?
