Today, calcium metal is usually prepared by electrolysis of fused calcium chloride to which a little calcium fluoride has been added. It is used in alloys with other metals, such as aluminum, lead, or copper; in preparation of other metals, such as thorium and uranium, by reduction; and (like barium) in the manufacture of vacuum tubes to remove residual gases.

Calcium metal work upon mechanical possessing. Bulk calcium i s soft, crystalline metal. It may be readily extruded o n heating to 420 – 460 0 C. X-ray diffraction pattern of
Calcium is a soft, silvery white, reactive metal that burns in air with a crimson flame. Its compounds are very common in the Earth''s crust. The name is from the Latin for stone. The Romans often used stones to count, so the word calculate is from the same root.
In a polluted atmosphere where the concentration of sulfur dioxide is high, calcium carbonate deteriorates more rapidly than in less polluted air. Similarly, phosphorus burns much more rapidly in an atmosphere of pure oxygen than in air, which is only about 20% oxygen.

tallizing metal upon contact with air oxygen. In addition, the calcium passing into the film in the melting process provokes formation of a very coarse and friable film on the surface of
C Argon is less dense than air. D Argon produces light when it burns. 24 Metals W, X, Y and Z are reacted with dilute hydrochloric acid. The oxides of metals W, X, Y and Z are heated with carbon.
Calcium, vital for cellular function, is an alkaline earth metal in group 2, period 4, and the s-block of the periodic table. In elemental form, it is a reactive metal that burns with a bright orange-red flame when heated in air.
Coal burns in air to form carbon dioxide gas. Hydrogen burns in the presence of oxygen to form water in the form of steam. Upon cooling, it becomes liquid. Formation of Ammonium chloride:Ammonium chloride is formed by coining vapours of ammonia with
