About The Elements

Carbon

Atomic Number: 6

Atomic Mass: 12 amu

Symbol: (C)

Uses: Carbon forms a large number of compounds, more than any other element. Because of its willingness to bond to other nonmetallic elements it is often referred to as the building block of life

Who Discovered it? Known since ancient times.

Number of Valence Electrons: 4

Silicon

Atomic Number: 14

Atomic Mass: 28 amu

Symbol: (Si)

Uses: In nature, silicon is no loner. It's usually found linked up with a pair of oxygen molecules as silicon dioxide, otherwise known as silica

Atomic Number: 32

Atomic Mass: 73 amu

Symbol: (Ge)

Uses: fluorescent lamps and some LEDs and solar panels

Tin

Atomic Number: 50

Atomic Mass: 119 amu

Symbol: (Sn)

Uses: Archaeological evidence suggests that people have been using tin for at least 5500 years. Tin is primarily obtained from the mineral cassiterite (SnO2) and is extracted by roasting cassiterite in a furnace with carbon. Tin makes up only about 0.001% of the earth's crust and is

Lead

Atomic Number: 82

Atomic Mass: 207 amu

Symbol: (Pb)

Uses: Lead is a soft, malleable, ductile (drawn out into a thin wire) and heavy metal. It initially has a bluish-white color that tarnishes to a dull gray color when exposed to air. It is corrosion resistant and when melted into a liquid has a shiny chrome-silver look.
