Calcium was known as early as the first century when the Ancient Romans prepared lime as calcium oxide.

Calcium was first isolated by Sir Humphry Davy in 1808 when he electrolyzed a mixture of lime and mercuric oxide.

Davy was trying to isolate calcium; when he heard that Jöns Jakob Berzelius and Pontin prepared calcium amalgam by electrolyzing lime in mercury, he tried it himself. От латинского слова калькс - лайм 31 1875 Paul-Emile Lecoq de Boisbaudran France From the Latin word "Gallia" meaning "France" and perhaps also from the Latin word "gallus"

Calcium is considered to be non-toxic
The shell of an egg is made up of primarily calcium carbonate
Calcium is used to remove oxygen, sulfur and carbon from alloys.

It is also used as an alloying agent used in the production of aluminum, beryllium, copper, lead, and magnesium alloys.

Calcium is used as a reducing agent in the extraction of other metals, such as uranium, zirconium, and thorium.

Calcium carbonate is used in manufacturing cement and mortar, lime and limestone.
