What happens when Metals are burnt in Air ?
Magnesium burns in air with a dazzling white flame. All metals react in the same manner

Almost all metals combine with oxygen to form metal oxides.
Metal + Oxygen → Metal oxide
For example, when copper is heated in air, it combines with oxygen to form copper(II) oxide, a black oxide.
2Cu + O2 → 2CuO
(Copper) (Copper(II) oxide)
Similarly, aluminium forms aluminium oxide.
4Al + 3O2 → 2Al2O3
(Aluminium) (Aluminium oxide)
