Group 1 elements reacting with water.

Potassium , Sodium, Lithium

1. potassium is the most reactive of the three

2. Sodium is the second most reactive

3. Lithium is the least reactive

THE WORD EQUATION OF THE THREE ELEMENTS

1. The word equation for the reaction between potassium and water is: Potassium + Water → Potassium Hydroxide + Hydrogen Gas.

2. The word equation for the reaction between lithium and water is: Lithium + Water → Lithium hydroxide + Hydrogen gas.

3. The word equation for when sodium reacts with water is Sodium + Water → Sodium hydroxide + Hydrogen.

Reactions of other metals with water

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

2. Magnesium reacts slowly with cold water to form magnesium hydroxide and hydrogen gas.

3. calcium is more reactive than magnesium.

4. The word equation for calcium reacting with water is Calcium + water → calcium hydroxide + hydrogen

5. Magnesium + boiling water -> magnesium hydroxide + hydrogen gas.

6. The reaction between magnesium and steam is more vigorous because steam particles have higher energy and move faster, leading to more frequent and forceful collisions with magnesium atoms.
