Question

Why is calcium found in the form of compound?

Answer 1

Hint: Calcium is a chemical element with the atomic number 20 and the symbol Ca.
Calcium is a silvery-white, soft metal that tarnishes quickly and reacts with water in the air. Other metals such as thorium and uranium are prepared using calcium metal as a reducing agent. Aluminum, beryllium, copper, lead, and magnesium alloys all use it as an alloying agent.

Complete answer:

Calcium is a reactive element since it easily loses two electrons to form the octet. Calcium does not exist in its pure form in nature, but it is easily dispersed in its compounds. Calcium is a metal that reacts strongly with water and a variety of other compounds. Calcium reacts with other elements in nature to form compounds because of its high reactivity. As it reacts with oxygen and water, it readily forms compounds.
Calcite (calcium carbonate) is found in limestone, chalk, granite, dolomite, eggshells, pearls, coral, stalactites, stalagmites, and the shells of many sea species on Earth as calcite (calcium carbonate). Calcium bicarbonate is formed when calcium carbonate deposits dissolve in carbon dioxide-rich water.

Note:
Calcium is not present in its elemental form, but it is abundant in rocks and minerals such as limestone (calcium carbonate), dolomite (calcium magnesium carbonate), and gypsum (calcium sulphate) (calcium sulfate). In the Earth's crust, it is the fifth most common feature.
