✔ 最佳答案
Y is group 2 metals, it will donate two electrons. then it will form cation with 2+ charge. when oxygen react will metals, it will gain two electrons. and form 2- charge.
due to oxygen gain two electrons form one Y metal. so the formula is YO.
And the bonding of it is ionic bond

YO <----
因為大家Y多左２粒electron,
但oxide 係 2-,
so using crossover method.
就會變左YO
Y - 2+
O - 2-

the formula of ions of Y then is Y2+ when the formula of oxide ions is O2-
So, YO
So, YO
