  1. Silicon(Si) By Johnny Colby and Michael Long

  2. Try Silicon • Abbreviation = Si • It’s the 2nd most element found inside the earth’s crust • It’s atomic mass is 28.0855 • It’s atomic number is 14 and it is a metalloid

  3. Properties Luster Shiny Conductivity Semiconductor Brittleness Brittle Hardness 7 on the Mohs Scale Color Silver State of Matter Solid Melting Point 1414° C Boiling point 3265° C Density 2.329 Combusting point -9055 J/(kg K)

  4. Discovery!!! • Silicon was first identified as an element in 1787 by Antoine Lavoisier. • However in 1800 Humphrey Davy believed silicon was a compound and not an element. • Gay-Lussac and Thénard tried to purify silicon in 1811 through heating potassium with silicon tetraflouride. • JonsBerzilius is credited with the discovery because he was the first one able to purify and get silicon through a similar method.

  5. Uses • Silicon valley is named that because of all the silicon chip manufacturers. That is one of the most popular uses of silicon • It is also found in quartz and other rocks and minerals. • Alloys such as aluminum-silicon mainly used in the automotive industry.
