Because important is the metal (sodium) and his spectral lines.
Sodium oxide does not burn itself, but it reacts with water or acids to produce sodium hydroxide and heat. This reaction is exothermic and can generate intense heat, enough to start a fire when sodium oxide comes in contact with a reactive substance.
Pure sodium chloride will burn and create a pure orange flame. If there are impurities present, you would see flickers or inconsistancies in the solid orange flame. Note, use a platinum wire to hold sample while burning, as a wooden split can cause these flickers if it starts to burn
Sodium chloride (NaCl) does not have a characteristic color when exposed to a flame test. Sodium compounds are usually identified by the strong yellow color they produce in a flame test due to the sodium ion.
A strong yellow color, from sodium
When sodium reacts with oxygen, it forms sodium oxide. The appearance changes because sodium oxide is a different compound with different properties compared to pure sodium. The increase in mass is due to the combination of the sodium atoms with oxygen atoms to form sodium oxide molecules.

Orangish yellow
Sodium Chloride, common table salt, will not burn.
When sodium oxide is burned, it typically produces a yellow flame.

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.
Depending on the metal in the chloride (Na, Ca, Sr, Li, ....).
Sodium chloride (NaCl) does not have a characteristic color when exposed to a flame test. Sodium compounds are usually identified by the strong yellow color they produce in a flame test due to the sodium ion.
Sodium oxide (Na2O) is not burnable.In contrast: it just is produced when burning sodium (Na) with oxygen (O2)
