Because important is the metal (sodium) and his spectral lines.
Sodium oxide (Na2O) is not burnable.In contrast: it just is produced when burning sodium (Na) with oxygen (O2)
It will burn
A strong yellow color, from sodium
When flame tested, Sodium ions range from a yellow to a bright orange flame and Potassium ions give a lilac or light purple flame. Neither the Sulphate nor the Chloride ions should have emission spectra in the visible range.
The flame test for strontium - a strong red color.

Orangish yellow
Sodium Chloride, common table salt, will not burn.

Sodium chloride doesn't burn.
Yes. To burn a compound you need a halogen with a higher energy than the one in the salt. So if you put sodium chloride in a fluorine rich environment and apply a flame it will burn.
