Cov ntsiab lus uas yog metals zoo li plam electrons thiab dhau los ua qhov zoo ions hu ua cations. Cov ntsiab lus uas tsis yog hlau zoo li tau txais cov khoom siv hluav taws xob thiab ua tsis zoo ions hu ua anions. Cov hlau uas nyob rau hauv kem 1A ntawm lub sij hawm lub sij hawm tsim ions los ntawm poob ib electron.
Qhov twg ntawm cov ntsiab lus hauv qab no muaj qhov nyiam plam electron?
Francium muaj qhov nyiam tshaj plaws los plam electrons.
Qhov twg ntawm cov ntsiab lus hauv qab no feem ntau yuav plam electrons?
Tshwj xeeb, cesium (Cs) tuaj yeem tso nws cov valence electron yooj yim dua li lithium (Li). Qhov tseeb, rau cov hlau alkali (cov ntsiab lus hauv pawg 1), qhov yooj yim ntawm kev muab cov hluav taws xob sib txawv raws li hauv qab no: Cs > Rb > K > Na > Li nrog Cs feem ntau yuav, thiab Li qhov tsawg tshaj plaws yuav poob ib qho hluav taws xob.
Lub caij twg feem ntau muab cov electrons?
Teb: Cov ntsiab lus uas yog nonmetals zoo li nce electrons thiab dhau los ua qhov tsis zoo ions hu ua anions.
Cov ntsiab lus twg zoo li nce electrons?
teb. Teb: Cov ntsiab lus uas yog nonmetals zoo li nce electrons thiab ua tsis zoo ions hu ua anions.
