Polyatomic ions muaj tshwj xeeb npe . Ntau ntawm lawv muaj cov pa oxygen thiab hu ua oxyanions. Thaum sib txawv oxyanions yog ua los ntawm tib lub caij, tab sis muaj ntau cov pa oxygen atoms, ces ua ntej thiab suffixes yog siv los qhia lawv sib nrug.
Ib sab ntawm qhov no, koj puas siv cov lus ua ntej thaum naming ionic compounds?
Ua tsis yog siv tus lej ua ntej xws li mono-, di-, tri-, thiab lwm yam thaum npe ionic compounds - cov no tsuas yog siv hauv npe covalent molecular tshuaj sib xyaw.
Ib yam li ntawd, vim li cas peb tsis siv cov lus ua ntej rau cov ionic compounds? Tsis txhob siv prefixes qhia seb muaj pes tsawg ntawm txhua lub ntsiab lus tam sim no; cov ntaub ntawv no yog implied nyob rau hauv lub npe ntawm lub compound . vim hlau tuaj yeem tsim ntau dua ib qho nqi. Ionic compounds Muaj cov hlau thiab polyatomic ion.
Ib tug kuj yuav nug, dab tsi yog txoj cai rau naming polyatomic ions?
Txoj cai 1. Lub cation yog sau ua ntej ntawm lub npe; lub anion yog sau thib ob hauv lub npe. Txoj cai 2. Thaum cov qauv ntsuas muaj ob lossis ntau dua ntawm tib yam polyatomic ion , uas ion yog sau nyob rau hauv kab lus nrog cov subscript sau sab nraum cov kab lus.
Dab tsi yog 3 txoj cai rau naming acids?
Qhov peb lub ntsiab lus sib txawv uas ua tau rau cov anions ua rau peb txoj cai hauv qab no
- Thaum lub anion xaus rau hauv -ide, lub npe acid pib nrog prefix hydro-.
- Thaum lub anion xaus rau hauv -ate, lub npe ntawm cov kua qaub yog lub hauv paus ntawm anion ua raws li cov lus -ic.

Thaum naming ib hom 1 ionic compound Koj npe li cas cov hlau ion?
Ionic tebchaw yog cov sib txuas nruab nrab uas ua los ntawm cov khoom zoo ions hu ua cations thiab tsis zoo them ions hu ua anions. Rau binary ionic compounds (ionic compounds uas tsuas muaj ob hom ntawm cov ntsiab lus), cov tebchaw muaj npe los ntawm kev sau lub npe ntawm cov cation ua ntej tom qab lub npe ntawm cov anion
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv.
