they burn and sometime change colour or state, but they do this at a higher teperature
Typically when a metal 'burns', what is happening is that it is getting hot enough for it to react and form a bond with the oxygen in the atmosphere. This is almost identical to what happens when metal rusts, but on a much shorter time scales because of the higher energies involved. In other words, the metal is forming a chemical bond with the oxygen in the air.
Magnesium is a metal when we say burning of magnesium it means formation of its oxide with liberation of heat and light.

burns
Magnesium burns bright white. It is often used in the production of fireworks. Magnesium is the most common metal that burns white, but titanium , aluminum , and beryllium can be mixed to form compounds that also form bright white light.
