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.
