+1 for each Na
-1 for each O (peroxide)
+1 for each Na -1 for oxygen (as it is peroxide)
The principal oxidation state of NA in NA2O2 and K in KO2 is +1
The chemical formula of sodium peroxide is Na2O2.
3 Na2O2 is 3 molecules of sodium peroxide.
oxidation number of I is -1. oxidation number of F is +1.
+1 for each Na -1 for oxygen (as it is peroxide)
The principal oxidation state of NA in NA2O2 and K in KO2 is +1
The oxidation number of any free element is 0. So if it is oxygen by itself (e.g., O2) then the oxidation number/state is 0. In its compounds the oxidation number of oxygen is -2. This rule only stands if it isn't a peroxide such as H2O2 or Na2O2, in peroxide cases, the oxygen is -1.
The chemical formula of sodium peroxide is Na2O2.
3 Na2O2 is 3 molecules of sodium peroxide.
