A few metals, such as gold, silver, and copper can be found in pure form as metal elements. Nuggets or flakes of these metals can be taken straight from rock, but this is uncommon. Metals are used to make many familiar things around us, such as copper in electrical wires, aluminum in soda cans, iron in saucepans, and solid gold in jewelry.

Calcium - Wikipedia

It is the fifth most abundant element in Earth''s crust, and the third most abundant metal, after iron and aluminium. The most common calcium compound on Earth is calcium carbonate, found in limestone and the fossilised remnants of early sea life; gypsum, anhydrite, fluorite, and apatite are also sources of calcium.

Water Quality Notes: Alkalinity and Hardness

polyvalent ions in fresh water are calcium (Ca++) and magnesium (Mg++). Hardness is usually divided into two egories: carbonate hardness and noncarbonate hardness. Carbonate hardness is usually due to the presence of bicarbonate [Ca(HCO 3) 2 3) 2 3
