Ans: Cesium tsis nruab nrab, nws muaj 1 valence electron . Cesium tsis yog nruab nrab, vim nws tsis yog ib qho roj av zoo. Nyob rau hauv thiaj li yuav tau ib tug nruab nrab nws yuav tsum tau muaj 8 valence electrons , Cesium nkaus xwb muaj 1.
Ib yam li ntawd, koj tuaj yeem nug, Lewis lub cim rau cesium ion yog dab tsi?
Cesium ion

Tom qab ntawd, lo lus nug yog, yuav ua li cas cesium ua ib qho ion? Cesium yog qhov feem ntau electropositive thiab feem ntau alkaline caij, thiab yog li, yooj yim dua li tag nrho lwm cov ntsiab lus, nws poob nws ib leeg valence electron thiab cov ntaub ntawv. ionic bonds nrog ze li tag nrho cov inorganic thiab organic anions.
Ib yam li ntawd, pes tsawg protons thiab electrons nyob hauv Cs + ion?
| Lub npe | Cesium |
|---|---|
