Lub tswv yim ntawm electronegativity tau qhia los ntawm Linus Pauling hauv xyoo 1932; ntawm Pauling nplai, fluorineyog muab ib qho electronegativity ntawm 3.98, thiab lwm cov ntsiab lus raug ntsuas txheeb ze rau tus nqi ntawd. … Yog li, fluorine yog cov khoom siv hluav taws xob ntau tshaj plaws, thaum francium yog ib qho ntawm cov electronegative tsawg tshaj plaws.
Yuav ua li cas 3 lub ntsiab muaj qhov siab tshaj plaws electronegativity?
Cov ntsiab lus los ntawm pawg halogen suav nrog F, Cl, Br muaj qhov zoo nkauj electronegativities. Cov khoom siv hluav taws xob feem ntau 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.
Qhov twg muaj qhov siab tshaj plaws electronegativity O lossis S?
O yog electronegative tshaj S. Yog li ntawd, los ntawm kev soj ntsuam peb tuaj yeem hais tias cov pa oxygen yog cov khoom siv hluav taws xob tshaj plaws.
Lub ntsiab lus twg muaj qhov siab tshaj plaws electronegativity N lossis O?
Vim li cas oxygen ntau electronegative dua nitrogen? Oxygen muaj 8 protons nyob rau hauv lub nucleus thaum nitrogen tsuas muaj 7. Ib tug khub yuav muaj kev attraction ntau dua los ntawm oxygen lub nucleus dua los ntawm nitrogen, thiab yog li ntawd lub electronegativity ntawm oxygen yog ntau dua.
Yuav ua li cas yog electropositive feem ntau?
- Caesium, Cs yog cov khoom siv hluav taws xob zoo tshaj plaws hauv lub sijhawm. Nws belongs rau thawj pab pawg neeg thiab thib rau lub sij hawm nyob rau hauv lub periodic rooj. Nws tuaj yeem yooj yim pub dawb nws ib qho hluav taws xob hluav taws xob kom tau txais cov khoom siv roj zoo.
