# Net ionic equation for a synthesis reaction?

In the following reaction

$$\ce{S (s) + O2 (g) -> SO2 (g)}$$

there are no spectator ions because both $\ce{S}$ and $\ce{O2}$ take part in the reaction. Does that mean the net ionic equation is the same as the molecular equation?

I think there should not be a net ionic equation at all, because there are no ions in the reactants.
