Cov txheej txheem rau npe ib qho kev sib koom ua ke yog: thaum npe ib complex ion, cov ligands npe ua ntej cov hlau ion. Sau tus npe ntawm ligands nyob rau hauv cov nram qab no kev txiav txim: nruab nrab, tsis zoo, zoo. Yog tias muaj ntau lub ligands ntawm tib hom nqi, lawv yog npe nyob rau hauv alphabetical kev txiav txim.
Ib yam li ntawd, kev sib koom ua ke nrog piv txwv yog dab tsi?
Kev sib koom ua ke suav nrog cov tshuaj xws li vitamin B12, hemoglobin, thiab chlorophyll, dyes thiab pigments, thiab catalysts siv los npaj cov organic. Kev sib koom ua ke muaj lub hauv paus hlau atom puag ncig los ntawm nonmetal atoms los yog pawg ntawm atoms, hu ua ligands.
Tom qab ntawd, lo lus nug yog, qhov kev sib koom ua ke txhais li cas?:ib compound los yog ion nrog lub hauv paus feem ntau yog xim hlau atom lossis ion ua ke los ntawm koom tes bonds nrog tus naj npawb ntawm cov ions nyob ib puag ncig, pawg, lossis molecules. - hu ua kev sib koom ua ke.
Xav txog qhov no, koj ua li cas lub npe ntawm cov khoom siv hlau?
Lub npe Ionic Compounds nrog Transition Hlau
- Sau lub npe ntawm kev hloov pauv hlau raws li qhia nyob rau ntawm Lub Sijhawm Lub Sijhawm.
- Sau lub npe thiab them nyiaj rau cov tsis yog hlau.
- Siv tag nrho cov nqi ntawm cov hlau tsis yog hlau (los yog polyatomic ion) nrhiav tus nqi ntawm cov hlau hloov.
Dab tsi yog hom ligands?
Hom ntawm Ligands
- Unidentate ligands: Ligands nrog tsuas yog ib qho pub dawb atom, piv txwv li. NH3, Cl-, F- lwm.
- Bidentate ligands: Ligands nrog ob lub atoms pub dawb, piv txwv li. ethylenediamine, C2O42-(oxalate ion) thiab lwm yam.
- Tridentate ligands: Ligands uas muaj peb lub atoms pub dawb rau ib ligand, xws li. (dien) Diethyl triamine.

Dab tsi yog lub tswv yim ntawm kev txhawb nqa ntawm kev sib cais ntawm kev sib deev?
Kev txhawb zog yog cov txheej txheem los ntawm kev xaiv ntuj tsim kom muaj kev sib cais ntawm kev sib deev. Kev txhawb zog tuaj yeem tshwm sim raws li hauv qab no: Thaum ob pawg neeg uas tau khaws cia sib nrug, rov qab los rau hauv kev sib cuag, qhov kev sib cais ntawm cov menyuam yaus yuav ua tiav lossis tsis tiav. Yog tias nws ua tiav, speciation tau tshwm sim
Vim li cas txoj kev sib koom tes sib koom ua ke tseem ceeb?
Kev kawm Interdisciplinary tso cai rau kev sib txuas ntawm cov tswv yim thiab kev sib txuas ntawm cov yam ntxwv los ntawm ntau yam kev qhuab qhia. Nyob rau tib lub sijhawm nws hais txog cov tub ntxhais kawm qhov sib txawv ntawm tus kheej thiab pab tsim cov txuj ci tseem ceeb, hloov pauv tau
Nws txhais li cas thaum kev sib raug zoo ntawm kev sib raug zoo ua kev cuam tshuam?
Kev sib raug zoo ntawm ob tus neeg uas txhua tus neeg nyob ntawm thiab tau txais kev txhawb zog, txawm tias muaj txiaj ntsig lossis kev puas tsuaj, los ntawm lwm tus. ib qho kev sib cuam tshuam lossis kev sib raug zoo ntawm ob tus neeg, pab pawg, thiab lwm yam
Lub dav hlau sib koom ua ke tuaj yeem pab koj txiav txim siab li cas cov tog neeg sib koom ua ke?
Muab ob daim duab peb sab ntawm lub dav hlau sib koom ua ke, koj tuaj yeem tshawb xyuas seb lawv puas sib haum los ntawm kev siv cov qauv nyob deb kom pom qhov ntev ntawm lawv sab. Yog hais tias peb khub ntawm sab yog congruent, ces daim duab peb sab yog congruent los ntawm saum toj no theorem
Vim li cas koj tig lub cim tsis sib xws thaum koj sib npaug lossis faib los ntawm qhov tsis zoo?
Thaum koj muab ob sab los ntawm tus nqi tsis zoo koj ua rau sab uas ntau dua muaj 'loj' tus lej tsis zoo, uas txhais tau tias tam sim no tsawg dua lwm sab! Qhov no yog vim li cas koj yuav tsum tig lub cim thaum twg koj muab los ntawm tus lej tsis zoo
