Californium (Cf)
 Bronze – Bronze is usually made from about 78% copper and 12% tin. The less tin, the softer the metal will be, so usually no more than 28% tin is added. Bells are often made from bronze. This is the Liberty Bell in Philadelphia.
Bronze
An alloy mainly of copper and tin. C
Cadmium (Cd)
Element 48 on the periodic table. A silvery-white metal and one of the transition metals.
Cadmium is a soft metal with a low melting point. Friedrich Stromeyer, a German chemist, discovered it in 1817.
Cadmium is used for electroplating steel, iron, copper, brass and other alloys to protect them from corrosion. Because
it absorbs neutrons, cadmium also goes into control rods
in nuclear reactors.
Calcium (Ca)
Element 20 on the periodic table. A silvery alkaline-earth metal (group 2 element).
First isolated by British scientist Sir Humphry Davy in 1808, it does not occur as a native metal, but in compounds, of which calcium carbonate (limestone) is the most common. Bones are made of calcium phosphate. As calcium oxide (lime), it goes into cement and as a fertiliser.
 Calcium – Calcium carbonate makes limestone rocks and the calcite that forms fossils and crystals.
 Calcium – Calcium metal quickly tarnishes in air.
 Calcium – Calcium phosphate is the main constituent of bones.
Californium (Cf)
Element 98 on the periodic table. An artificial metallic radioactive element in the actinide series. It
is a transuranium element and makes a very intense source of light in medicine.
