3.2.5 The Reactivity Series

. . The Reactivity Series The reactivity series is a list of metals arranged in the order of their decreasing activities. After performing displacement experiments (Activities . and . ), the following series, (Table . ) known as the reactivity or activity series has been developed. Table .
