✔ 最佳答案
Because the cation , Aluminium ion ,
has a charge of 3+.
The anion ,
oxide ion ,
has a charge of 2-.
In order to have a balance of charge ( = 0 ) ,
there must be 2 Al ion and 3 O ion.
PS : The ration must be in the simpest ratio.

AL2O3唔係名稱咁簡單@@
佢係鋁同氧既化合物
化表有2個鋁同3個氧
因為AL係帶3個正電荷而氧係帶2個負電荷
所以需要2個鋁同3個氧去形成AL2O3
