The magnesium and the powder produced by burning it is an Element, compound.

A burning magnesium ribbon produces light of sufficient intensity to cause temporary vision loss. Do not look directly into the light source. Burning magnesium in the air produces intense heat that can cause burns and ignite combustible materials. When magnesium reacts with oxygen it emits a bright light that can temporarily blind you.

Magnesium burns very brightly because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium donates two electrons to oxygen-producing powdered magnesium oxide. Combustion of magnesium ribbon in the air is a chemical change for the following reasons: It is an irreversible change because once the ribbon burns it cannot be reignited. A new product with new properties is created.
