Ionic compounds yog nruab nrab tshuaj sib xyaw ua los ntawm kev them nqi zoo ions hu ua cations thiab negatively them ions npe anions. Rau binary ionic compounds ( ionic compounds uas tsuas muaj ob hom ntawm cov ntsiab lus), cov cov tshuaj muaj npe los ntawm kev sau ntawv npe ntawm cation thawj zaug ua raws li cov npe ntawm anion.
Tsis tas li ntawd, koj ua li cas lub npe ionic compound?
Yog koj xav tau npe ionic compound , pib los ntawm kev sau cov qauv rau qhov ntawd compound . Sau tus npe ntawm cov hlau, kuj hu ua cation. Cov cation yog qhov zoo them ion nyob rau hauv compound , thiab nws yeej ib txwm sau ua ntej. Tom ntej no, sau tus npe ntawm nonmetal, los yog anion.
Ib sab saum toj no, dab tsi yog daim ntawv tseem ceeb rau cov npe ntawm cov ionic compounds uas muaj cov hlau uas tsuas yog ib hom ion? Cov daim ntawv tseem ceeb rau cov npe ntawm Hom II ionic compounds yog kom muaj npe ntawm hlau cation ua ntej, ua raws li tus nqi ntawm lub hlau cation hauv parenthesis siv cov lej roman, thiab thaum kawg tus npe base ntawm nonmetal anion nrog -ide txuas qhov kawg ntawm nws.
Kuj kom paub, cov cai hauv kev naming ionic compounds yog dab tsi?
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 npe cov anion; qhov no yog ib qho nonmetal. Hloov cov lus rau '-ide,' lossis siv lub npe polyatomic anion.
Dab tsi yog ionic formula?
Zuag qhia tag nrho ionic formula rau ib lub compound yuav tsum yog hluav taws xob nruab nrab, txhais tau tias nws tsis muaj nqi. Thaum sau ntawv qauv rau cov ionic compound, cation los ua ntej, ua raws li cov anion, ob qho tib si nrog cov lej subscripts los qhia tus naj npawb ntawm atoms ntawm txhua tus.

Thaum naming ib compound nrog ib tug kev hloov hlau yuav xav tau dab tsi?
Tus yuam sij rau naming ionic compounds nrog kev hloov pauv hlau yog los txiav txim siab tus nqi ionic ntawm cov hlau thiab siv cov lej roman los qhia tus nqi ntawm cov hlau hloov pauv. 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
Vim li cas peb thiaj li kho cov coefficients thaum ntsuas cov tshuaj sib npaug thiab tsis yog cov ntawv sau npe?
Thaum koj hloov cov coefficients, koj tsuas yog hloov tus naj npawb ntawm cov molecules ntawm cov khoom tshwj xeeb. Txawm li cas los xij, thaum koj hloov cov ntawv sau npe, koj tab tom hloov cov tshuaj nws tus kheej, uas yuav ua rau koj qhov sib npaug tshuaj tsis raug
Cov qauv dab tsi thaum koj nchuav hlau filings nyob ib ncig ntawm cov hlau nplaum?
Thaum cov ntaub ntawv hlau tau nchuav ib ncig ntawm cov hlau nplaum, cov duab ntawm cov hlau nplaum raug ntes. Vim li cas qhov no tshwm sim? Tsis tas li ntawd, cov ntaub ntawv hlau no cais ua cov qauv pom tseeb ntawm cov kab
Cov yam ntxwv twg ntawm cov hlau atoms pab piav qhia vim li cas valence electrons hauv cov hlau yog delocalized?
Ib daim ntawv cog lus hlau yog kev sib koom ntawm ntau cov khoom siv hluav taws xob sib cais ntawm ntau cov ions zoo, qhov twg cov electrons ua raws li 'cov kua nplaum' muab cov khoom tsim nyog. Nws tsis zoo li covalent lossis ionic bonding. Cov hlau muaj zog ionization tsawg. Yog li ntawd, valence electrons tuaj yeem raug delocalized thoob plaws hauv cov hlau
Tam sim no universal naming system siv rau naming kab mob yog dab tsi?
Nyob rau hauv 1758, Linnaeus tau npaj ib qho kev faib cov kab mob. Nws luam tawm nyob rau hauv nws phau ntawv, Systema Naturae. Hauv qhov system no, txhua hom tau muab lub npe ob feem; Vim li no, qhov system hu ua binomial nomenclature. Cov npe yog raws li cov lus thoob ntiaj teb: Latin
