Because there are now 2 magnesiums and 2 oxygena after they have reacted
Ionic, Mg2+ and O2-
Half equations ?? The chemical formula of magnesium oxide is MgO.
This compound is magnesium oxide - MgO.
6
the Lewis formula for MgO is Mg2+[O]2- Which mean Mg loses 2 electrons and O gains 2 electrons to be stable.
i don't know whether there exists Alo,all i study so far is Al2O3both MgO and Al2O3 are ionic compouds. Al3+ is smaller than Mg2+(due to higher proton charge thus attracts the electrons closer),thus the ionic bonds in Al2O3 is greater thus it is harder.
MgO is an ionic compound.
water [H20]
MgO Magnesium Oxide.

The compound is called: magnesium oxide. Therefore, there are magnesium and oxygen atoms in the compound. The ions are: Mg2+ and O2-.
The balanced equation for the reaction between MgO and H2O is MgO + H2O -> Mg(OH)2.
