You think probable to magnesium.
Magnesium.
That could fit several metals. Iron burns brightly if it is powdered, but doesn't react with water unless oxygen is present. Aluminium is not easy to ignite but can burn very brightly when it does go, and it certainly doesn't react with water at room temperature, and zinc is similar. I suspect the questioner may be wanting the answer magnesium, as that is the one we see burning extremely brightly in the lab. However it does react with water, though rather slowly if the water is cold and the magnesium is covered with its normal oxide layer.
Metal reacting with oxygen is known as oxidation. A common form of this process is found in the rusting of iron, where the iron reacts with oxygen to form iron oxide (known as rust).
Oxygen.
The metal of copper can react with oxygen. This is a metal that is very reactive when ti is combined with different substances.
For example uranium react with oxygen but not with water.
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.
Magneseum. an Alkali earth metal
A metal that does not react to acid, oxygen or water does not exist.
no
Certain gases that react with oxygen, for example hydrogen.
Gold is a metal that does not react with oxygen when heated, even at high temperatures. This is because gold is a noble metal with low reactivity.
