In the reactivity series, the alkali metals are the most reactive, while the noble metals are the least reactive. The activity series of metals, also called the reactivity series, is a ranked list of metals ordered from most reactive to least reactive. The reactivity series is a systematic arrangement of metals and nonmetals in order of their decreasing chemical activity. Also known as the activity series , it helps predict how a substance will react with others, particularly in displacement reactions. This series determines the ability of a metal to replace another in a reaction and indicates how it interacts with oxygen, water (cold, hot, or steam), and acids. Chemistry revolves around chemical reactions, where substances interact to form ... The table summarises some reactions of metals in the reactivity series . Hydrogen and carbon are shown for comparison. There is no unique and fully consistent way to define the reactivity series , but it is common to use the three types of reaction listed below, many of which can be performed in a high-school laboratory (at least as demonstrations).
