Reactivity Series of Metals

Front

Learning objectives of the reactivity series

Back

- Predict the products of the reaction of a metal with water. - Write a word equation for the reaction of a metal with water. - Use the reactivity series to predict how vigorously metals react with acids, oxygen, and water.

Reactivity series definition

Back

The reactivity series lists metals in order of how vigorously they react with other substances. Metals at the top have very vigorous reactions, while those at the bottom react less.

Front

Reaction of calcium with water

Back

Calcium reacts with water to produce calcium hydroxide and hydrogen gas.

Front

Reaction of magnesium with steam

Back

Magnesium reacts with steam to produce magnesium oxide and hydrogen.
