Answer:
Sodium and potassium
Explanation:
On adding potassium to water, it melts and floats. The piece of potassium floats on the surface of water while moving quickly. The ignition of hydrogen is an instant reaction and the metal also sparks up with purplish flames.
When sodium comes in contact with water, it forms a ball and floats and fizzes rapidly. The presence of gas can be confirmed by setting fire to it because it burns with an orange flame.
