Na2O2 is the molecular formula of sodium peroxide.
The valency of sodium Na is +1 and the valency of peroxide is -2,so if you subtract +1 and -2 you will get -1 so according to criss cross method :
+1 -2
Na O2
According to what I said above that -1will go to sodium so therefore it becomes Na2O2
Hope this helps you......................
