Electronegativity yog hais txog lub peev xwm ntawm lub atom los nyiam cov khoom siv hluav taws xob sib koom hauv cov ntawv cog lus. … (Helium, neon, thiab argon tsis tau teev nyob rau hauv Pauling electronegativity scale, txawm hais tias nyob rau hauv Allred-Rochow nplai, helium muaj qhov siab tshaj plaws electronegativity.)
YPuas neon muaj 0 electronegativity?
Tsis yog, neon gases tsis suav nrog hauv electronegativity. Qhov no yog vim hais tias lawv tau sau lawv cov valence shells yog li lawv tsis tas yuav nyiam electrons thiab electronegativity yog lub peev xwm ntawm lub atom kom tau txais ib qho hluav taws xob.
Puas yog neon electropositive lossis electronegative?
For ex: Mg nrog tus lej atomic=12 muaj E. C=2, 8, 2 yog li nws muaj 2 valence electrons thiab li no tuaj yeem yooj yim plam lawv kom tau txais cov roj zoo ntawm Neon (2, 8). Yog li, nws yog electropositive hauv xwm.
Pob cov pa roj zoo muaj hluav taws xob?
Noble gases muaj ib qho electronegativity.
Pab pawg twg muaj qhov hluav taws xob siab tshaj plaws?
Ntawm cov ntsiab lus tseem ceeb, fluorine muaj qhov siab tshaj plaws electronegativity (EN=4.0) thiab cesium qis tshaj (EN=0.79).
