Yankho: Aluminiyamu ili mu gulu IIIA la tebulo la periodic kotero ili ndi valence itatu ma elekitironi. The chizindikiro cha aluminiyamu ndi Al omwe adzazunguliridwa ndi atatu madontho. 2.

Dziwaninso kuti chizindikiro cha dontho la elekitironi ndi chiyani?

Dothi la electron Zomangamanga - Zida zothandiza poganizira za mgwirizano. Mapangidwe a madontho a electron - valence ma elekitironi akuimiridwa ndi madontho anayikidwa mozungulira mankhwala chizindikiro. Ma electron amayikidwa awiri mbali iliyonse ya elemental chizindikiro kwa opambana asanu ndi atatu, omwe ndi chiwerengero cha ma elekitironi mu chipolopolo chodzaza s ndi p.

Kachiwiri, chithunzi cha madontho a elekitironi cha nayitrogeni ndi chiyani? Zithunzi za Electron Dot

lithiamu 1 s 2 2 s 1 1 electron ya valence
beryllium 1 s 2 2 s 2 2 ma elekitironi a valence
nayitrogeni 1 s 2 2 s 2 2 p 3 5 ma elekitironi a valence
neon 1 s 2 2 s 2 2 p 6 8 ma elekitironi a valence

Komanso funso ndilakuti, ndi ma elekitironi angati omwe amaimiridwa mu kapangidwe ka Lewis ka aluminium AL?

Izi zikutanthauza kuti alipo 13 ma elekitironi mu atomu ya aluminiyamu. Kuyang'ana pachithunzichi, mutha kuwona kuti pali ma elekitironi awiri mu chipolopolo chimodzi, eyiti mu chipolopolo chachiwiri, ndi atatu mu chipolopolo chachitatu.

Kodi pali kusiyana kotani pakati pa cation ndi anion?

Anion vs. cation. Ma ion amachokera ku maatomu kapena mamolekyu omwe apeza kapena kutaya ma elekitironi amodzi kapena angapo a valence, kuwapatsa chiwongola dzanja chabwino kapena cholakwika. Iwo ndi a zoipa mlandu amatchedwa anions ndi izo ndi a ndalama zabwino zimatchedwa cations.
