Discovered in 1808 by Sir Humphrey Davy in London. Calcium is a silvery white metal which is obtained by the electrolysis of molten calcium chloride. It is one of the most abundant metal elements on Earth (41000 ppm), but it never occurs as the pure element, the main deposits being limestone (CaCO3), Dolomite (CaCO3.MgCO3) and Gypsum (CaSO4.2H2O).

Oct 09, 2003· Hat''s off to Chev/Tex. I, too have heard that calcium compounds tend to be "softer" on/to metals. But what we are talking about are periodic table group IIA elements attached to organics (carbon) rings/chains - what effect does the compound molecule have. rather than just the soft metal group IIA selection? Can we try this with Sr?
The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C (39 o F) as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below:
