Use the following observations to construct the correct reactivity series according to their increasing reactivity.

1. Calcium + Water : React less violent

2. Potassium + Water: React very violent

3. Copper + Water: No reaction

4. Zinc + Water: Quite slow with steam

• Sodium>Copper>Potassium>Calcium

• Copper>Zinc>Calcium>Potassium

• Zinc>Copper>Potassium>Calcium

• Potassium>Calcium>Zinc>Copper
