Reactivity series of metals

Order of reactivity Metal Reactions with water or steam

↑ sodium (Na) vigorous reaction with cold water

↓ calcium (Ca) less vigorous reaction with cold water

least reactive magnesium (Mg) slow reaction with cold water, vigorous with hot water

Step-by-step explanation:

Sodium reacts explosively with cold water.

On the other hand, metals such as iron do not react with cold water or hot water. However, it reacts with steam to give their respective oxides and hydrogen gas. Thus, metals react with water to form metal oxides and hydrogen gas.
