Ntawm cov ntsiab lus tseem ceeb, fluorine muajsiab tshaj 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.
Koj paub li cas lub caij twg muaj electronegativity siab dua?
Ntawm lub sijhawm teem sijhawm, electronegativity feem ntau nce ntxiv thaum koj txav los ntawm sab laug mus rau sab xis hla ib lub sijhawm thiab txo qis thaum koj txav mus rau ib pawg. Raws li qhov tshwm sim, cov ntsiab lus electronegative feem ntau pom nyob rau sab xis saum toj ntawm lub rooj zaum, thaum lub ntsiab lus electronegative tsawg tshaj plaws pom nyob rau hauv qab sab laug.
Lub ntsiab lus twg muaj qhov zoo tshaj plaws electronegativity?
Electronegativity nce hauv qab mus rau saum hauv pab pawg, thiab nce ntawm sab laug mus rau sab xis hla lub sijhawm. Yog li, fluorineyog cov khoom siv hluav taws xob tshaj plaws, thaum francium yog ib qho ntawm cov electronegative tsawg tshaj plaws.
Qhov twg muaj ntau dua electronegativity O lossis S?
Yog vim li cas oxygen yog electronegative ntau dua sulfur: Oxygen muaj 2 qib zog, sulfur muaj 3. sulfur's bonding electrons. Li no cov pa oxygen yog ib qho electronegative atom ntau dua.
Vim li cas electronegativity ntawm O siab dua C?
Nyob hauv pawg carbonyl,oxygen yog electronegative ntau dua carbon thiab li no cov electrons sib txuas tau nyiam ntau dua rau oxygen. … Cov kev sib txuas ntawm cov electrons yuav muaj kev nyiam ntau dua los ntawm oxygen lub nucleus uas los ntawm carbon, yog li cov electronegativity ntawm oxygen ntau dua.
