Si-Silicon By: Sem Lanning 6p

For my adopt-an-element project I got the 14th element, Silicon.

  • Silicon is a metal in the semi-metal part of the periodic table.
  • Silicon has the atomic number of 14 and an rounded atomic mass of 28. The real mass is 28.0855.
  • The melting point is 1687 K or 1414 °C and it has a Boiling Point of 3538 K or 3266 °C.
  • The normal phase of silicon at room temperature is solid.
  • It has a silvery color and has a hardness of 7 mohs.
  • Fun fact: Liquid silicon is denser than solid silicon.

Mohs is a hardness scale used for minerals. Quartz is a mineral and is crystalline silicon dioxide which is crystal SiO2. That's how to measure the mohs for silicon.

This is Jons Jacob Berzelius
  • The word Silicon came from the latin word "Silex" (Flint).
  • Silicon was discovered by Jons Jacob Berzelius, a swedish scientist.
  • He was born on August 20, 1779 near Linkoping, Sweden and died on August 7 1848 in Stockholm, Sweden.
  • Silicon was discovered in 1824. I couldn't find out where but I infer in Stockholm since he studied and live there.
  • Discovered by heating chips of potassium in a silica container and then carefully washing away the residual by-products
How to make a PV panel (solar panel) with silicon


  • It causes the building up of connective tissues and bones.
  • Silicon is also good for taking care of nails, hair and skin.
  • Silicon is also vital for the preventing of atherosclerosis, insomnia, skin disorders and tuberculosis.


  • Silicon is also used for Silicone rubber.
  • Silicone rubber is used in automobiles, textiles, construction and achitecture
  • Also household products like hair conditioner, clothing (protection from wrinkles and stains), detergents, fabric softeners.
  • Even deodarant, antiperspirant, cosmetics, and moisturizers.
  • It also, as the picture above shows, makes solar panels.
  • Silicon is also used in computer chips, the human body, stone and sand porcelain, glass etc. There are too many to name.
  • Silicon is the second most abundant element in the earth's crust.

3 interesting facts about silicon

1. Silicon is vital for life in both plants and animals 2. Silicon has a higher density in liquid form than in solid form 3. Silicon is the main element in many meteorites. - This is the link to the Silicon adopot-an-element info sheet.
