Electronegativity nce hauv qab mus rau saum hauv pab pawg, thiab nce ntawm sab laug mus rau sab xis hla lub sijhawm. Yog li, fluorine yog cov khoom siv hluav taws xob tshaj plaws, thaum francium francium Francium yog cov tshuaj lom neeg nrog lub cim Fr thiab atomic tooj 87. Ua ntej nws nrhiav pom., nws tau raug xa mus rau eka-caesium. Nws yog qhov tsis tshua muaj hluav taws xob; nws cov isotope ruaj khov tshaj plaws, francium-223 (keeb kwm hu ua actinium K tom qab lub ntuj decay saw nyob rau hauv), muaj ib nrab-lub neej ntawm tsuas yog 22 feeb. https://en.wikipedia.org › wiki › Francium
Francium - Wikipedia
yog ib qho ntawm qhov tsawg tshaj plaws electronegative.
Yuav ua li cas ntawm cov hauv qab no muaj lub siab tshaj plaws electronegativity?
Ntawm cov ntsiab lus tseem ceeb, fluorine muaj qhov siab tshaj plaws electronegativity (EN=4.0) thiab cesium qis tshaj (EN=0.79). Qhov no qhia tau hais tias fluorine muaj lub siab nyiam kom tau txais cov hluav taws xob los ntawm lwm cov ntsiab lus nrog qis electronegativities. Peb tuaj yeem siv cov txiaj ntsig no los twv seb yuav ua li cas thaum qee cov ntsiab lus sib xyaw ua ke.
Lub ntsiab lus twg muaj qhov siab tshaj plaws electronegativity thiab yog vim li cas?
Cov khoom siv hluav taws xob ntau tshaj plaws yog Fluorinenrog tus qhab nia ntawm 4.0 (qhov siab tshaj plaws tau.) hla ntawm Fluorine peb kuj muaj N thiab O nrog cov electronegativities siab. Electronegativity yog qhov tseem ceeb npaum li cas cov ntsiab lus 'xav' electrons.
Yam twg muaj qhov thib ob siab tshajelectronegativity?
Oxygen yog qhov thib ob feem ntau electronegative keeb tom qab fluorine.
Lub ntsiab lus twg muaj qhov quizlet siab tshaj plaws electronegativity?
Lub caij twg muaj qhov zoo tshaj plaws electronegativity? fluorine. Cov ntsiab lus electronegative feem ntau yog nyob rau sab xis saum toj ntawm lub rooj zaum.
