Detailed Solution

Concept- Silvery-white calcium is a delicate, easily tarnished metal that reacts with atmospheric water. Calcium metal is used as a reducing agent while creating other metals like thorium and uranium. It is used as an alloying agent in alloys of aluminium, beryllium, copper, lead, and magnesium.
Due to its ease in losing two electrons to create the octet, calcium is a reactive element. Although it doesn't occur in nature in its purest form, calcium is easily dissolved in its compounds. Metal calcium has a potent chemical reaction with water and numerous other substances. Due to calcium's great reactivity, it combines with other elements in nature to create compounds. It easily forms compounds as a result of its reactions with oxygen and water.
Hence, the correct answer is option (2).
