Which Metal Is Most Easily Oxidized?

Oxidation is a reaction of a metal with oxygen to form an oxide. The rate of oxidation depends on the reactivity of the metal, meaning how easily the metal undergoes the chemical reaction. Active metals, such as potassium and lithium, are highly reactive and easily oxidized. The more active a metal is, the more difficult it is to control the rate of oxidation. In general, the more reactive a metal is, the more easily it undergoes oxidation. The least reactive metals, such as gold and platinum, are the most difficult to oxidize.

The most common type of metal oxidation is called corrosion. It happens when a metal reacts with oxygen in the presence of water. This reaction produces a new substance on the metal's surface that is different from the metal itself. The new substance is usually weaker than the metal, and it can cause the metal to break down over time.

The prognosis for metal oxidation is largely dependent on the type of metal involved. For example, metals like iron and steel are highly susceptible to rusting, while other metals like aluminum are much more resistant. In general, however, the prognosis for metal oxidation is not particularly positive. Over time, all metals will eventually succumb to corrosion and oxidization, and will need to be replaced.
