Vim li cas thiaj tsis muaj ionic daim ntawv cog lus ntawm cov poov tshuaj thiab magnesium? Ob leeg yog hlau thiab form cations. Ib daim ntawv cog lus ionic tsuas yog nruab nrab ntawm ions ntawm cov nqi sib txawv.
Yuav ua li cas lub caij yuav tsim ib daim ntawv cog lus ionic nrog magnesium?
Ionic compounds
Magnesium thiab chlorine hnov mob tsim magnesium chloride.
Yuav ua li cas ua daim ntawv cog lus ionic nrog potassium?
Tam sim no, thaum potassium reacts nrog chlorine, tus qub poob nws cov valence electron thiab tom kawg yuav siv nws. Ob qhov ions tshwm sim, piv txwv li cov poov tshuaj cation thiab cov tshuaj chloride anion, yog tom qab ntawd sib koom ua ke los ntawm electrostatic quab yuam ntawm attraction → ib daim ntawv cog lus ionic yog tsim.
Puas magnesium thiab sodium ua ionic bonds?
Muaj lub zog hluav taws xob muaj zog ntawm kev nyiam ntawm cov ions oppositely them - qhov no yog hu ua ionic daim ntawv cog lus. Cov slideshow qhia tau hais tias ionic bonds raug tsim nyob rau hauv sodium chloride, magnesium oxide thiab calcium chloride.
Lub atoms twg tsim ib daim ntawv cog lus ionic?
Ionic bonds yog tsim los ntawm kev sib pauv ntawm valence electrons ntawm atoms, feem ntau a hlau thiab nonmetal.
