Which is the correct chemical equation for the following statement Sodium reacts with oxygen in 2 to 1 ratio to produce sodium oxide?

For my convenience, I will take it as a number of molecules of both. So you will have sodium oxide formed out of two giving out heat energy. ( Once you take out sodium of rock oil, it will automatically burn out. ) The chemical equation will be

4 Na + O 2 = 2 Na 2 O.
