Ernest Z. Lub tswv yim ntawm kev sib cog lus ionic tsim maj mam dhau xyoo. Nyob ib ncig ntawm 1830, Michael Faraday qhov kev sim ntawm electrolysis pom tias qee yam khoom yuav ua rau hluav taws xob thaum yaj hauv dej. Nws xav tias hluav taws xob ua rau cov khoom tawg mus rau hauv cov khoom siv hluav taws xob.
Leej twg nrhiav tau ionic thiab covalent bonds?
American chemist G. N. Lewis yog qhov tseem ceeb hauv kev tsim txoj kev xav ntawm covalent bonding. Lub ntsiab lus ntawm chemical bonding yog lub hauv paus ntawm chemistry. Xyoo 1916 Gilbert Newton Lewis (1875–1946) tau luam tawm nws daim ntawv qhia hais tias cov tshuaj lom neeg yog ib khub ntawm electrons sib koom los ntawm ob lub atoms.
Leej twg piav qhia txog kev tsim cov ntawv cog lus ionic?
Lewis, uas tau piav qhia txog kev tsim cov ntawv cog lus zoo li no los ntawm kev nyiam ntawm qee cov atoms ua ke nrog ib leeg txhawm rau kom ob leeg muaj cov qauv hluav taws xob ntawm cov neeg muaj txiaj ntsig zoo. -gas atom.
Electrovalent bond Wikipedia yog dab tsi?
electrovalent bond (ionic bond) Ib hom tshuaj tiv thaiv tsim los ntawm kev hloov ntawm ib lossis ntau dua electrons los ntawm ib lub atom mus rau lwm qhov, kom cov ions oppositely raug tsim. … Cov electrostatic attraction ntawm cov ions no muab kev sib txuas hauv NaCl.
NaCl Electrovalency yog dab tsi?
So Na+ + Cl-=NaCl Electrovalency yog ib qho kev ntsuas ntawm tus nqi hluav taws xob ntawm ib qho ion thiab yogsiv thaum ntsuas tshuaj tiv thaiv. Electrovalency muaj feem xyuam nrog cov ntsiab lus ntawm electronegativity thiab valence electrons, thiab qhia cov xov tooj ntawm electrons tsim nyog rau ib qho ion kom muaj hluav taws xob sib npaug.
