Carbon-C Name: Carbon Symbol: C Atomic Number: 6 Element Classification: Non-metal Physical Properties: Soft, dull gray or black, density= 2.267 g/mL Chemical Properties: Carbon burns to form CO2 or CO, combines with other elements. Spectral Lines of Carbon

Spectral lines of Silicon Silicon-S Name: Silcon Symbol: S Atomic Number: 14 Element Classification: Metalloid Physical Properties: Gray and metallic appearance, density= 2.329 g/cm3 Chemical Properties: Combines with other elements. Spectral lines of Silicon

Germanium- Ge Name: Germanium Symbol: Ge Atomic Number: 32 Element Classification: Metalloid Physical Properties: Bright, shiny, silvery color. Brittle and breaks apart. Chemical Properties: Inactive, does not dissolve with water or react with oxygen at room temperature.

Tin- Sn Name: Tin Symbol: Sn Atomic Number: 50 Element Classification: Post-Transition Metals Physical Properties: Malleable, silvery white metal. Chemical Properties: Forms a protective oxide film so it resists corrosion by water but will corrode in acids, alkalis and salts.

Lead- Pb Name: Lead Symbol: Pb Atomic Number: 82 Element Classification: Post-Transition Metals Physical Properties: Bluish white metal, bright luster, very soft. Chemical Properties: Very resistant to corrosion.

Ununquadium- Uuq Name: Ununquadium Symbol: Uuq Atomic Number: 114 Element Classification: Post-Transition Metal. Physical Properties: Metallic, silvery white or grey, properties similar to lead and tin. Chemical Properties: Unstable.

GENERAL PROPERTIES Vary in Physical and Chemical properties. Relatively unreactive. Tend to form covalent bonds. Some semi-conductors and poor conductors of heat and electricity. Generally soft, malleable. Occur in nature in elemental and combined forms. Covalent Bonding

USES Carbon is used for drill bits and machine parts. Silicon is used to make ceramics and glass. It is used to make concrete and brick. Tin is used to plate iron cans to keep them from rusting. Lead used to be used in pipes, because it is unreactive, it is not used anymore because it is toxic. Germanium is a rare element that is used to manufacture semi-conductor devices. Drill Bits

INTERESTING FACTS Carbon as diamond is the hardest known naturally occurring substance. Silicon is found in beach sand. Tin is a superconductor at low temperatures. The discovery that lead is toxic to humans has led to the development of unleaded gasoline and paint.

CONCLUSION The carbon family is made up of a nonmetal, metalloids, and metals. Properties vary in the elements of the group, but they are generally unreactive. The elements of carbon, silicon, and germanium have become very important in electronics and computers. Ununquadium is unstable and radioactive.
