Txoj Kev Npaj Sau Npe
Ib ionic compound yog npe thawj los ntawm nws cov cation thiab tom qab ntawd los ntawm nws cov anion. Cov cation muaj tib yam npe raws li nws lub ntsiab. Piv txwv li, K+1 hu ua poov tshuaj ion , ib yam li K hu ua potassium atom.
Tib neeg kuj nug, dab tsi yog txoj cai hauv kev naming ionic compounds?
Thaum naming ionic compounds, peb ua raws li cov kev cai dav dav:
- Txheeb xyuas thiab muab lub npe cation; Qhov no yog cov khoom hlau lossis polyatomic cation.
- Txheeb xyuas thiab muab lub npe anion; qhov no yog ib qho nonmetal. Hloov cov lus rau '-ide,' lossis siv lub npe polyatomic anion.
Kuj Paub, dab tsi yog cov ions nquag?
- lead (IV) ion.
- tin (IV) ion.
- mercury (I) ion *
- manganese (II) ion.
- cobalt (III) ion.
- tooj liab (II) ion.
- hlau (III) ion.
- manganese (III) ion.
Tsis tas li ntawd, lub npe ntawm pb4+ yog dab tsi?
Piv txwv li, Fe2+ yog hu ua ferrous ion, thiab Fe3 + yog hu ua ferric ion; Cu + yog cuprous ion, thiab Cu2 + yog cupric ion.
Lub npe ntawm ion K + yog dab tsi?
Potassium ion | K+ - PubChem.

Koj npe cycloalkenes thiab alkenes li cas?
Lub ene suffix (kawg) qhia tias alkene lossis cycloalkene. Cov saw ntev tshaj plaws xaiv rau lub hauv paus npe yuav tsum suav nrog ob qho tib si carbon atoms ntawm ob daim ntawv cog lus. Lub hauv paus saw yuav tsum tau suav los ntawm qhov kawg ze tshaj ntawm ob daim ntawv cog lus carbon atom
Dab tsi yog cov txheej txheem uas nitrate ions thiab nitrite ions hloov mus rau nitrous oxide gas thiab nitrogen gas n2?
Nitrate ions thiab nitrite ions raug hloov mus rau nitrous oxide gas thiab nitrogen gas (N2). Cov cag ntoo nqus ammonium ions thiab nitrate ions siv los ua cov molecules xws li DNA, amino acids, thiab cov proteins. Organic nitrogen (cov nitrogen hauv DNA, amino acids, proteins) tawg mus rau ammonia, ces ammonium
Koj npe li cas rau txhua hom kev sib txuas?
Hom Cov Khoom Siv Hlau + Nonmetal -> ionic compound (feem ntau) Hlau + Polyatomic ion -> ionic compound (feem ntau) Nonmetal + Nonmetal -> covalent compound (feem ntau) Hydrogen + Nonmetal -> covalent compound (feem ntau)
Yuav ua li cas koj lub npe acids nrog polyatomic ions?
Naming Acids Ib qho polyatomic ion nrog cov lus "-ate" siv cov lus "-ic" ua cov kua qaub. Thaum koj muaj polyatomic ion nrog ib qho oxygen ntau dua li "-ate" ion, ces koj cov kua qaub yuav muaj lub npe "per-" thiab cov lus "-ic." Piv txwv li, chlorate ion yog ClO3
Dab tsi yog lub npe rau cov khoom uas yaj hauv dej tab sis tsis tsim ions lossis ua hluav taws xob tam sim no?
Ib qho electrolyte yog ib yam khoom uas tsim cov kua hluav taws xob thaum yaj hauv cov kuab tshuaj polar, xws li dej. Cov yaj electrolyte cais mus rau hauv cations thiab anions, uas disperse uniformly los ntawm cov kuab tshuaj. Hluav taws xob, xws li kev daws teeb meem yog nruab nrab
