Mg is a Group II metal, and forms the ion Mg^2+. Oxygen forms the ion O^2-. A compound of them would be MgO.
2Mg + O2 ---> 2MgO
S can form more than one oxide: SO, SO2 and SO3.
2S + O2 ---> 2SO
S + O2 ---> SO2
2S + 3O2 ---> 2SO3

Magnesium:

2Mg + O2 ==> 2MgO

You got the combustion of sulphur correct.
