Ionic Kev sib txuas lus yog kev hloov pauv ntawm valence electron (s) ntawm atoms. Nws yog ib hom tshuaj daim ntawv cog lus uas generates ob oppositely them ions . Hauv ionic bonds, cov hlau poob electrons los ua ib tug zoo them cation, whereas lub nonmetal txais cov electrons los ua ib tug negatively charged anion.
Thiab cov lus nug yog, dab tsi yog ionic compound nrog piv txwv?
Ionic compounds yog tshuaj sib xyaw suav nrog ions . Ob lub ntsiab lus tshuaj sib xyaw feem ntau yog ionic thaum ib lub caij yog hlau thiab lwm yam yog tsis yog hlau. Piv txwv muaj xws li: sodium chloride: NaCl, nrog Na+ thiab Cl- ions . magnesium oxide: MgO, nrog Mg2+ thiab O2- ions.
Tsis tas li ntawd, yuav ua li cas rau electrons hauv ib qho ionic compound? Ionic compounds yog tsim los ntawm kev tsim ntawm qhov zoo thiab qhov tsis zoo ions . Hluav taws xob tau kis los ntawm ib lub atom mus rau lwm qhov los tsim cov pa roj tsawg hluav taws xob cov qauv rau txhua tus ion . Lub atom uas tsim ib tug zoo ion poob electrons mus rau lub atom uas nce electrons tsim kom muaj qhov tsis zoo ion.
Ib yam li ntawd, koj tuaj yeem nug, koj yuav piav qhia txog ionic compound li cas?
Ionic compounds yog tshuaj sib xyaw ua los ntawm ions . Cov no ions yog atoms uas nce lossis poob electrons, muab lawv tus nqi zoo lossis tsis zoo. Cov hlau zoo li plam electrons, yog li lawv dhau los ua cations thiab muaj cov txiaj ntsig zoo. Nonmetals zoo li tau txais electrons, tsim cov anions uas muaj tus nqi tsis zoo.
Yuav ua li cas thaum koj yaj lub ionic compound?
Khoom ionic compounds tsis ua hluav taws xob vim lub ions (them nqi) raug kaw rau hauv ib lub lattice lossis array. Thaum rhuab, lub ionic khov kho yaj los ua kua, los yog molten, ionic compound . Cov ions nyob rau hauv molten, los yog kua, ionic compound muaj kev ywj pheej txav tawm ntawm lub lattice qauv.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Yuav ua li cas tshwm sim thaum ib tug muaj zog acid yaj nyob rau hauv dej?
Thaum cov kua qaub yaj hauv dej, ib qho proton (hydrogen ion) raug xa mus rau cov dej molecule los tsim cov hydroxonium ion thiab qhov tsis zoo ion nyob ntawm seb cov kua qaub koj pib li cas. Cov kua qaub muaj zog yog ib qho uas yuav luag 100% ionised hauv kev daws. Lwm cov tshuaj muaj zog muaj xws li sulfuric acid thiab nitric acid
Yuav ua li cas yog lub sum ntawm cov atomic masses ntawm tag nrho cov atoms nyob rau hauv ib tug qauv rau ib tug compound?
Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formula thiab qhia nyob rau hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass
Yuav ua li cas tshwm sim thaum ib tug tam sim no nqa coil muab tso rau hauv ib tug magnetic teb?
Yog tias tus neeg nqa khoom nqa tam sim no tau muab tso rau hauv qhov chaw sib nqus, nws ntsib lub zog Lorentz (tshwj tsis yog lub kaum sab xis ntawm qhov ntws ntawm tam sim no thiab cov kab hlau nplaum yog 0 °)
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
