Calcium

Calcium is a chemical element with the symbol Ca and atomic number 20. It is an essential element for living organisms, especially for the growth and maintenance of healthy bones and teeth. Calcium also plays a crucial role in various physiological processes, including muscle contraction, nerve function, and blood clotting.

Properties of Calcium

Calcium is a soft gray alkaline earth metal. It is the fifth most abundant element in the Earth's crust and is essential for the construction of shells and exoskeletons of various organisms. In its pure form, calcium is a silvery-white metal that is relatively reactive and easily forms compounds with other elements.

Uses of Calcium

Calcium has numerous industrial and biological applications. Some common uses of calcium include:

• Production of steel and aluminum alloys
• Manufacture of cement, mortar, and concrete
• Production of calcium carbonate, used in the paper, plastics, and paint industries
• Dietary supplement for humans and animals
• Water treatment to neutralize acidity
