Tsim ib qho Ion Ib lub atom uas poob ib lossis ntau dua valence electrons los ua ib qho txiaj ntsig zoo ion yog lub npe hu ua cation, thaum lub atom uas tau txais electrons thiab ua tsis zoo them yog hu ua anion.
Dab tsi poob electron hauv kev sib txuas?
Cov ntsiab lus uas feem ntau nyiam plam electrons thaum ua cov ntawv cog lus nrog lwm cov ntsiab lus hu ua cations Cov no yog cov hlau nquag. … Cov ions ntawm cov hlau uas tsim tom qab poob cov electron yog hu ua cations, thaum uas tsis yog-metallic ions-tsim tom qab tau txais electron(s)-yog hu ua anions.
Lub caij twg feem ntau yuav poob ib qho hluav taws xob?
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.
Puas atom plam electrons?
Qee zaum atoms nce lossis poob electrons. Lub atom ces poob los yog nce nqi "tsis zoo". Cov atoms no hu ua ions. Positive Ion - tshwm sim thaum lub atom poob ib qho hluav taws xob (tus nqi tsis zoo) nws muaj protons ntau dua li electrons.
Lub ntsiab lus twg yuav muaj feem yuav nce electrons?
Chlorine feem ntau yuav tau txais ib qho hluav taws xob. Xav txog lub zog lub xeev ntawm ib lub atom, lub plhaub tag nrho yog qhov ruaj khov heev.
