Question

What is sodium + oxygen when doing ionic bonds

Answer 1

When burning sodium (Na) in oxygen (O2), you get sodium oxide (Na2O) and/or sodium peroxide (Na2O2). At high pressures, you can additionally get sodium superoxide (NaO2).

4 Na + O2 → 2 Na2O, and then partially 2 Na2O + O2 → 2 Na2O2.

Under normal conditions, approximately 20% of the mixture is Na2O2.

6 Na + 2 O2 → 2 Na2O + Na2O2
