To use this method, the absolute value of the oxidation number of the first ion is used as the subscript of the second, and vice versa. The subscripts are then reduced by the greatest common factor. For instance, to find the formula for aluminium oxide: :The oxidation number of Al is +3 and oxygen is -2. Criss cross the absolute values to give Al2O3 To find the formula for magnesium oxide:- :The oxidation number of Mg is +2 and oxygen is -2. Criss cross the absolute values to give Mg2O2 :In this example there is a common factor of 2 so divide by 2 to give MgO. It is a helpful method just cross them and put them down without charges. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Crisscross method」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
