    At room temperature, a sample of pure magnesium metal combines with oxygen to form a thin skin of magnesium oxide. At higher temperatures, it burns with a blinding white light, and because of this property it's used in fireworks.  Read more at the link:

    2Mg + O2 -> 2MgO (Magnesium Oxide)

    But we all know that air is made not only of O2, but N2 too. The O2 is responsible for combustion; the N2, however, is unreactive at normal temperatures.

    When we burn Mg in the air, the result will be 2 products: magnesium oxide (MgO) and magnesium nitride (Mg3N2).
