When Magnesium ribbon is burnt in air, it combines with oxygen to form white powder Magnesium oxide (MgO) with the release of heat and light. The magnesium oxide forms a white powder. To form this powdery substance, magnesium gives off two electrons to oxygen atoms.
2Mg+O2⟶2MgO
The colour produced by the burning of the magnesium ribbon is white and white ash is also produced.
