Ib yam li ntawd, nws raug nug, dab tsi yog qhov kev teeb tsa hluav taws xob rau BE?
[Nws] 2s2
Tsis tas li ntawd, qhov tseeb hluav taws xob teeb tsa ntawm atomic tooj 20 yog dab tsi? Electronic Configurations ntawm Cations thiab Anions Piv txwv li, hauv av xeev electronic configuration calcium (Z = 20 ) yog 1s 22s ib 22 ib p 63s ib 23 ib p 64s ib 2. Calcium ion (Ca 2+), txawm li cas los xij, muaj ob lub electrons tsawg dua.
