The activity series of metals is an empirical tool used to predict products in displacement reactions and reactivity of metals with water and acids in replacement reactions and ore extraction. It can be used to predict the products in similar reactions involving a different metal.

The first five elements are highly reactive metals that will react with cold water, hot water, and steam to form hydrogen gas and hydroxides.
The next four metals (magnesium through chromium) are active metals that will react with hot water or steam to form their oxides and hydrogen gas. All the oxides of these two groups of metals will resist reduction by H2 gas.
The six metals from iron to lead will replace hydrogen from hydrochloric, sulfuric and nitric acids.
